I use SONOS and MC all the time. (That's all I use). A stereo One set up. A 5.1 theatre arc setup and two moves.
Yes, you get each speaker listed separately (except the arc setup), but if you group (at least for the ones), only the SONOS group name is listed in playing now. That's very nice. Same for the group name of the theatre setup - really nice. However, the MOVE speakers behave differently and show up separately in playing now, even if group named (the SONOS group name appears twice). Worse, one of the group names will generally not play and the other one will - so that is a a pain. Solution that I did. find out which one doesn't work and use MC to rename it in MC to something like "Don't Use". Then it is not confusing.
I have also tried the MC linking with the Move and the SONOs Ones. Easy to link but there are huge timing problems that the adjustments in MC don't seem to be able to resolve (the timing seems to periodically change). But this combination of MC and SONOS is wonderful.
