There are rumours that Sonos are considering opening up their platform to 3rd-party developers. Given they have recently dropped the bridge requirement, and the abundance of AirPlay-compatible speakers (plus WiFi-direct based alternative to Sonos, Panasonic have released one) I think they are perhaps starting to feel the competitive heat.
