>The media center will be able to support multiple independent outputs, meaning that you can for instance listen to radio in the kitchen, some music in another room and watch TV in the livingroom.

>That's partially here, e.g. www.sonos.com. In my case I prefer wired, so in the NZ house we went with Nuvo Grand Concerto. Using winamp and a soundblaster, you can feed 3 or more audio channels into it from one PC.

As far as I can see, the Sonos box is only an audio center. If you look more closely at the specs I mention, you will see that it will practically replace most of your current audio, TV and PC hardware. You end up with ONE box, plus loudspeakers, monitor(s), a remote control and a keyboard. You can throw out your stereo, TV, VCR, DVD/CD/HD-player/recorder, satelite tuner, cable tuner, cable modem, PCs, routers, everything....!

And, of course wireless is user selectable, if you want cables you can have them.
