I'll have to admit that's a little beyond what I have setup at my house. I was hoping someone else would chime in with a suggestion. Hint, hint, Wink, wink, Nudge, nudge.
The one thing I've set up in the past is using a plug in for winamp to remotely control winamp on another computer. I haven't used it since I shuffles around the computers and can't quite reach the stereo like I used to.
