Now Sonos music systems support playback directly from the iPad, please could you integrate Djay in to Sonos too?
There would be a lag on the playback (due to the way Sonos buffers music in order to sync between Zones) which would make DJing impossible/painful.
n.b. I already tried this with the Line In option on a Sonos Connect player.
There is integration with Spotify in Sonos. If it could be combined with Djay pro it would be quit simple to make a dicision simple.
