You can get Sonos Desktop to run on CrossOver if you do the following:
1) Create an empty Windows 7 bottle, I named mine 'Sonos'
2) Install .NET framework
3) Install Sonos Desktop from http://www.sonos.com/redir/controller_software_pc
The program runs well and even installs updates to itself and the system components successfully.
I was unable to access the crosstie editor for this app, hence this post.
