Anyone know of a some cheap magic boxes that would allow me to stream audio from my PC to my home stereo without running any wires? I imagine one box would plug into my current soundcard and the other box would just plug into my stereo. This is my preferred solution so that I can use all the features of the soundcard. Alternatively, it could just emulate a soundcard on my PC and use WiFi to do the transmission to the box connected to the stereo. I guess another possibility would be for the box on the PC to be a USB device.
My goal is to remote the output of music applications and things like Internet radio to my home stereo in the next room.
