Subsonic Forum

Is this already possible?

If not, I think it would be a great feature to consider adding. For example, my brother (who lives across town) has a Subsonic server running. I want to add his Subsonic server (using the username/password he created for me) as a Music source on my XBMC.

This is kind of tricky actually. Subsonic I think is merely intended to serve music over HTTP and not implement something like the UPnP protocol. You need something more like TVersity or http://www.nero.com/enu/mediahome4-introduction.html

The only way I see this working is if an XBMC script is written to interact with the Subsonic API. You could suggest this on the XBMC forums and see if there isn't some more interest there.

UPnp protocol to interact with XBMC (or other softwares) will be great new feature!!!
