Thanks for all the info. The Roku Soundbridge looks nice but if i am thinking correctly, that doesn't really directly interface with MC14 or does it? I assume that it has it's own remote? For now, i think that i will use some audio cables that i have to run from an external sound card on my pc to my receiver. That will give me 3 audio zones:
1:Computer Room
2:Receiver Room (Great Room) via external sound card to receiver
3:Deck Outside (Zone provided by my receiver)
...and control it all with Rivermote. Rivermote combined with MC14 is really the deal maker for me in all of this as it provides a nice visual remote interface showing album art, tag information and providing volume and zone control in a compact form factor on my iPod Touch. much much cheaper than a Sonos system.....
If i want to add the video capabilities of MC14, then i'll add another pc in the Great Room.
Thanks again for all the helpful information.
