1. Company is 100% taken over.
2. Stock is declared void. Stockholders get a 1-time eminent domain payment of (value of company assets)-(cost to taxpayers for bailout)/(# shares outstanding). Frankly the stockholders should be happy they don't end up owing money which is what the math certainly will work out to.
3. Corporate officers arrested and face heavy criminal penalties. Costing the taxpayers billions of dollars needs to be made a serious crime. It is certainly worse than robbing the corner store.
4. Government runs company in such a way to preserve the general economy.
5. Eventually company is either dissolved or IPO'ed - with all proceeds going to taxpayers.
If this were how bailouts worked you wouldn't see too many executives asking for them.

I was not around for the debate that persuaded a Congress to enact Glass-Steagall and a range of other protections. But I was here when, in the early 1980s, it was decided that we should expand the opportunities for savings and loans to do certain things. And they began to broker deposits and they took off. They would take a sleepy little savings and loan in some town, and they would take off like a Roman candle. Pretty soon they would have a multibillion-dollar organization, and they would decide they would use that organization to park junk bonds in. We had a savings and loan out in California that had over 50 percent of its assets in risky junk bonds.
Let me describe the ultimate perversion, the hood ornament on stupidity. The U.S. Government owned nonperforming junk bonds in the Taj Mahal Casino. Let me say that again. The U.S. Government ended up owning nonperforming junk bonds in the Taj Mahal Casino in Atlantic City. How did that happen? The savings and loans were able to buy junk bonds. The savings and loans went belly up. The junk bonds were not performing. And the U.S. Government ended up with those junk bonds.
Was that a perversion? Of course it was. But it is an example of what has happened when we decide, under a term called modernization, to forget the lessons of the past, to forget there are certain things that are inherently risky, and they ought not be fused or merged with the enterprise of banking that requires the perception and, of course, the reality--but especially the perception--of safety and soundness.
Last year, we had a failure of a firm called LTCM, Long-Term Capital Management. It was an organization run by some of the smartest people in the world, I guess, in the area of finance. They had Nobel laureates helping run this place. They had some of the smartest people on Wall Street. They put together a lot of money. They had this hedge fund, unregulated hedge fund. They had invested more than $1 trillion in derivatives in this fund--more than $1 trillion in derivatives value.
Then, with all of the smartest folks around, and all this money, and an enormous amount of leverage, when it looked as if this firm was going to go belly up, just flat out broke, guess what happened. On a Sunday, Mr. Greenspan and the Federal Reserve Board decided to convene a meeting of corresponding banks and others who had an interest in this, saying: You have to save Long-Term Capital Management. You have to save this hedge firm. If you don't, there will be catastrophic results in the economy. The hit will be too big.
You have this unregulated risky activity out there in the economy, and you have one firm that has $1 trillion in derivative values and enormous risk, and, with all their brains, it doesn't work. They are going to go belly up. Who bears the burden of that? The Federal Government, the Federal Reserve Board.
We have the GAO doing an investigation to find out the circumstances of all that. I am very interested in this no-fault capitalism that exists with respect to Long-Term Capital Management. Who decides what kind of capitalism is no-fault capitalism? And when and how and is there a conflict of interest here?
The reason I raise this point is, this will be replicated again and again and again, as long as we bring bills to the floor that talk about financial services modernization and refuse to deal with the issue of thoughtful and sensible regulation of things such as hedge funds and derivatives and as long as we bring bills to the floor that say we can connect and couple, we can actually hitch up, inherently risky enterprises with the core banking issues in this country.

the housing bubble was primarily fueled by errors on Wall Street, not Washington.
There were three important Washington errors. Washington allowed banks to loan federally insured deposit money to companies with only securities (e.g. securitized mortgages) as a collateral. This put taxpayers on the hook and led to the Bear Stearns bail out.
The second Washington error was that even with the housing bubble, Washington left the reserve rate (how much banks have to hold of their deposits) at 15% rather than raising it. If they had raised the reserve rate, there would have been less money for loans and banks would have been more careful to whom they loaned it. As it was, banks were over capitalized and desperate to loan money.
The third Washington error was to make it more difficult to take bankruptcy. As a result, banks were more willing to loan money for over priced houses (figuring that they could grab other assets instead).
At the worst of the bubble, house prices were sixty percent over priced (using rental values for a comparison). House prices are still thirty percent over priced. They have more to fall before the market stabilizes. Unfortunately, most of the programs that are being launched are aimed at stabilizing house prices. This won't work until houses stop being over priced.
What Washington should be doing is helping house prices fall. One way that they could do that would be to amend bankruptcy laws back to their previous difficulty and add the ability for judges to adjust the principal of the loan down to the current value of the house. This would allow people to sell their houses after declaring bankruptcy (rather than taking a foreclosure). Too many people can't sell their houses because they owe more than the house is worth.

Interactive Brokers [interactivebrokers.com] has a Java-based
Trader Workstation [interactivebrokers.com] ("TWS") and they explicitly support Linux. They offer almost anything you can get anywhere, including mutual funds, stocks, options, futures (commodity & financial), currency, and foreign stocks. Commissions are 10x lower than Charles Schwab if you trade often (if you don't then a minimum monthly commission kicks in).
TWS is a large, cumbersome Java applet, but it works tolerably well on a fast machine (and there's not much alternative on Linux)
One annoyance is that they only support jdk 1.5.0_x (not the current 1.6.x), I think because of some concurrency bugs in their code (they claim the newer Java is buggy). However TWS generally does work with the latest jdk, but they won't support it.
IB's telephone support is sometimes rude, the opposite of "hand holding". I guess they have only a few over-worked support people to keep costs down. Also, they only provide on-line statements and never send physical mail except for annual 1099 tax forms. So, be sure your spouse/executor knows you have an IB account, because if you die there will be no monthly statements to clue them!
In summary, IB is good, despite their warts. If you trade a few times a month or more, it's worth the hassles.

Not to sound like an ass but anyone who is that serious about trading needs to invest in a Bloomberg terminal [billpapa.org]. If you are just dinking around - that's one thing. But the summary seems to indicate you are looking for a "serious" trading platform. Don't waste your time with FOSS. FOSS has it's place but a trading platform is not it. Go with a proven solution.
There are plenty of "active trader" platforms out there from a variety of brokers. Most that I have see are Java apps. I run Schwab's web-based active trading on Linux all the time but even it is a simplified version of the real thing.
Also, one more thing to consider: I would hate to find out that my FOSS trading platform had a bug. If it's bad enough, it could be devastating and totally wipe you out. Do you really want to take on that kind of risk? This really isn't the place to be "testing" your trading platform when real dollars are at stake.
Now....analysis is a different beast. FOSS might have a place there. I don't know but I see no reason to reinvent the wheel when there are FAR better solutions already out there. I have yet to see anything from FOSS that is compelling. And no -- MS Money/Quicken imitators are NOT what we are talking about here. Not even close.

That is the trading system I've spent several years working on is built entirely using Open Source tools and libraries. The system itself is not currently open, but that is a possibility we here certainly look favorably at.
As far as actual entire free trading systems, there is JavaTraders@googlegroups.com which is a good place to start. Also check out the quickfixj.org site, you will find some things there. There is also an Eclipse plugin which provides some level of GUI.
Frankly we didn't any of the code in any of those projects (although we do use ta-lib). But as I say, you can do a lot with ActiveMQ, any good open source RDBMS (PostgreSQL,MySQL) and your Enterprise Java framework bits of choice.
Basically if I were you I'd pick one of the java based projects that is kicking and does roughly what you want, the way you want to do it. For simple basic trading of one or two instrument classes you can probably put together something pretty workable.

I have not seen any open source projects that you can use as a platform for building a trading system.
I have built an intraday (within one day) trading system in Java. I'm afraid that this system is not open source either. This system runs one or more models that look for intraday trading signals. The Java software submits buy and sell orders. It is multi-threaded and runs one thread per stock. I have been very happy with the software performance. A long running "server" like this seems to benefit from Sun's HotSpot compiler. The system is web services based (e.g., it runs on Tomcat).
I used Interactive Brokers [interactivebrokers.com] for my market data and order infrastructure. I was concerned about the quality of the Interactive Brokers tick data (the trade by trade data). Interactive Brokers consolidates their tick data feed so you get a consolidated tick about ever 250 msec. For my system this has been adequate. If you want to run on Linux or use Java there are few inexpensive options for real time data feeds. Information may way to be free, but market data is expensive.
I have some web pages on the alternatives that I explored as platforms for a Java/Linux based trading system. These notes can be found on my web page Software for Constructing a Market Trading System [bearcave.com]

No good FOSS trading platform (yet) (Score:3, Insightful)
what FOSS software do you use for financial analysis, trading, system development, and testing in a Un*x environment?
I am aware of TA-Lib [ta-lib.org], QuantLib [quantlib.org] and libraries implementing the FIX protocol [fixprotocol.org] to be used in commercial products and private Un*x trading applications.
Sadly, most people looking for a solid FOSS trading platform will find that they need to roll up their sleeve to get something decent working.
I have found that software in this area seems quite sparse.
Indeed. I closely monitor the FOSS community since 1998 for a trading platform. What I observed was a lot of well intended projects, but even to these days, none did reach satisfying maturity.
I think it relates to under estimation of the complexity. Most project starts with a lot of energy then goes idle because of unattainable short-term goals.
A general purpose platform will not emerge until someone put coherently together existing building blocks instead of starting yet another weak trading platform from scratch.
Example of building block is the FIX protocol. Many FIX libraries have matured. Quantlib is another solid example.
My contribution to the whole picture is TA-Lib. It is a set of functions for people who care about technical analysis (shameless plug).
