I recently built the Murfie music service app for SONOS. You can go to a web page served by any SONOS device and tell it a url to treat as a music service. Code up a SOAP service there and you'll be able to do anything that any other music service does. I'd never done anything with SOAP before, so there was a bit of a learning curve, but once I got over that hurdle most of the other coding was fairly easy. Their developer portal explains basically all of the things you can do. Getting the service approved was the hardest part.
