mutliple sound cards, multiple music streams



New Member
i want to put speakers in each of 4 rooms of my house so I can pipe MP3 music from a PC (so i can remote control into it over my network and pick playlists, control volume, etc). but i don't want to commit 4 PC's and 4 sound cards to this project. Can I.....
1) put 4 sounds cards into one PC
2) run 4 instancer of a decent MP3 player (I like winamp and musicmatch jukebox, but i'm not excessively loyal to either one)
and now the $64 question
3) Can I pair off one player instance with one sound card, so that each room can hear their own individual music stream?

In addition to the "Can I" question, if I can, how do I do it?
