Found this site accidentally today. I'll want to look at it later. Sonos Multi Zone Digital Music System -play digital music from PC in any room The thing that I find interesting is that they present this as an "affordable" way to do distributed home audio. While I see the benefit from not having the wires (easier to setup); I don't see the "affordable" that they are touting. A single room would cost ~$499. That's not cheap IMO.
