I'm not familiar with the Belkin product. It seems like there are going to be allot of if-then limitations... Especially to eight zones/belkin players.
A quick look a the Belkin website has this which makes me think that it may not be all that easy...
"Connect with the Belkin SOUNDFORM App With our Belkin SOUNDFORM app for iOS and Mac devices, you can enjoy and control music in multiple rooms. It lets you tune sound, adjust latency, and sync all your AirPlay-enabled speakers automatically or manually."
If the Sonos app was too difficult, the Belkin app may be an issue also.
I'm Not an engineer, but I play one on TV. My handle is Tweety but I have nothing to do with the organization of similar name. I just had a really big head as a child so folks called me tweety bird.
