Hi GotCasaTunes,
I am afraid that we missed your posts, thinking they were the same as the posts here: http://www.casatunes.com/multi-room-audio/index.php/forums/viewthread/280/
In any case, we don’t have support at this time (see my response to scottleslie on the other thread).
Please accept our apologies for not responding faster. And, hopefully, we will have support for WHS2011 within a reasonable timeframe.
