silicon not in the v writes "Last night I was over at some friends' house. They had cable modem with no firewall and tons of spyware, etc. on their system. They complained about all the popups and how bad it was that they were afraid to let their kids on the computer, so I set them up with ZoneAlarm, Ad Aware, and Firefox to get it cleaned up. In return, the husband, who is a chiropractor, gave my wife and I a free adjustment. What other interesting services or benefits have people been able to get by bartering IT/programming services?"
