right, i thought the sonos could play different things to multiple zones simultaneously, for instance, - play one external hardrive, connected locally to it, in one zone, - another hardrive connected locally to it, to another, - a cell phone with its own library to a zone, - and a cell phone streaming internet radio to another zone. But I guess what you are saying is, i would need 4 sonos to do this? Also what ever app i used with the vera controller to control my lights etc.. would it also work well with the russound and the sonos. and if everything worked well together by the app control, would the russound keypads work well with the sonos? I really appreciate the help!
