Linux-to-Palm Integration?

Randseed asks: "I'm a physician and am looking to buy a PDA to make my life a lot easier. My entire computer network is based around Linux. The hospitals' are Windows, but I don't need to explicitly deal with them. This is where my fellow geeks at Slashdot come in. What kind of integration exists for PalmOS PDAs and Linux at this point? What do you guys use? What is the best way to deal with installing software on the Palm from a Linux machine?"
