By the way, you really should try out Playdar - it lets you stream your music on any of your computers from any of your computers. It also lets you stream from your friends, and there is a darknet plugin too. Even neater is how it interfaces with the web - you run a greasemonkey script for each website you want to use (say, Last.fm) which inserts a play link next to each track. The browser then talks to playdar which goes off, finds the song and streams it to you. It's really neat.
