Basically I'm trying to get the music from my desktop computer (in the bedroom) to my stereo (living room) while using the iPad as a remote. So far I've come up with using Audiogalaxy and bluetoothing that to a Bluetooth music receiver connected to my stereo. My only gripe with that is the Bluetooth music receiver. I've heard those things are pretty low quality devices.
Anyone have any other suggestions? I have a PS3 in the mix, but as far as a user interface is concerned I'd much rather be using the iPad.
