For a long time i'm searching for a solution to control Sonos with XBMC.

Like a lot of other people (with XBMC and a Sonossystem) we like to:

• selecting a song from the integrated musiclibrary from Sonos to play on the Sonos

• integrate the nowplaying feed from Sonos on XBMC

Finally i've found some information about a Python controller for Sonos!
