Like many users, we use Sonos in two different houses. We have two NAS's of music that I'm planning on keeping synchronized with RSYNC. What doesn't sync or cant get exported are Sonos Playlists. It would be great to be able to ad-hoc export them and then to import them as well. Using the UPnP interface, I've noted a Java program that can export playlists, but importing them is a bit troublesome. It would be great to have this feature.
