I have looked into this more than once. Have had CAIP's look into it and have talked directly with Sonos also.Apparently Sonos doesnt want to play with anybody. Closest I could come to internet streaming services hardware was a Sqeezebox module by Controlworks, but the Squeezebox hardware is a little flaky according to posts. Its too bad, I find Sonos to be a great product, but maybe a little greedy with their SDK's. Fear not though, there's plenty of overpriced media servers that integrate in a so-so fashion and dont offer Rhapsody, Pandora,LastFM, etc.
