I'm a newbie when it comes to home music/theater options. I could use some help. I've got a desktop Mac Pro in my office and a D-Link DIR-655 wireless router. I'd like to find a way to play music from my iTunes library on that computer in the living room, which is a few rooms away. I don't have a computer in the living room and don't particularly want one in there. What are my options? I guess I could get an iPod nano and some speakers and leave it at that. But is there any way to access my iTunes library without having a computer in there?
