Systems for a Geodesic Dome

We are building a Geodesic Dome.  My main system will end up in the master bedroom. My question is what do you think about Sonos systems and the connect amp they sell?
It would be nice to control music thru out the house with one system.  We would like to have probably 4 regions to the system.  I'll also need some bookshelf speakers or speakers I could hang or suspend for the main room.  I have not heard any sonos speakers but I'm thinking they would be ok for the kitchen and a smaller room.

Any suggestions?
 Thanks
