I have a Creative xmod wireless setup.
In my computer room, I have an old desktop that I use now as my media box, it has all my music on it. Attached to it is a Creative Xmod wireless transmitter:
About 17 yards away in my living room, I have my speakers attached to the Xmod receiver:
Across in the living room, I have my laptop that I use to remotely control Rhythmbox on the desktop wirelessly. So i can listen to music while working, or just enjoying a bottle of wine:) (and no, i wasn't drinking wine from that cup!)
