Yeah, that would work. I wonder what the processing loads would be? I 
assume that the sync has to be maintained on all outputs for all 
streams, independent of muting state. It also may not scale should I 
want to add more zones, but that's a while off. No better way to know 
than to try it.

I'll let you know what I find.

Thanks for the suggestions, I really appreciate it!
