Hello Iam in the middle of building a house and i add a home audio setup form www.integratedexcellence.com. I add speekers in every room of my house. I want to use my G4 mac to play the music thought the house. But i don't now how to do that. The speekers use cat5 from all the rooms and runs then to one place i picked out. what i want to do is play one play list for each room. My kids don't want to hear my music. Do i need to get a computer for each kid for there playlist. Or is there a program and some hardware i can get to play 4 plays list on one computer to each room ?
