I can't help you pthornhill but I've been thinking along the same lines myself.

If it were possible to just have basic transport commands and maybe even a current song/artist next in que display to be integrated into a multiroom control setup it would be better than nothing - which is effectively what we've got now.

So, if you have any success please keep us posted!


(actually, how ridiculous is it; that on a £1K remote - this is the best we can hope for usable control of Sonos - it's a joke)
