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.
"... They ne'er cared for us
yet: suffer us to famish, and their store-houses
crammed with grain; make edicts for usury, to
support usurers; repeal daily any wholesome act
established against the rich, and provide more
piercing statutes daily, to chain up and restrain
the poor. If the wars eat us not up, they will; and
there's all the love they bear us."
-- Shakespeare: Coriolanus, Act 1, scene 1
