I have done some searches on the forums, and read through multiple pages of topics and I see a trend.
There is a percentage of users who have requested "social" features be added to subsonic.
Why not do that to the core of what subsonic is about. Music.
So would it be possible to link Subsonics?
I have introduced subsonic to a few friends on the internet, like many of you probably have. They have gone off and redone their music collections with the proper tagging etc and have really nice music collections.
Can you imagine an easy interface to get to those face melting crunchy grooves? Bring all the Subsonics together, between trusted users, that want to "peer".
This opens the possibility of easy sharing and multiple social features many people are accustomed to today.
My subsonic acting as a distribution point for all my devices(other computers, android/IPhone,etc). My friends could build playlists and send me the playlist. I go to play it, my subsonic server connects to theirs and streams it from that server, to whatever endpoint I am using. I add a new album and I think its awesome, so I send out its playlist.
You could bring in the chat elements, but you might just be reinventing the wheel.
This idea might have already been proposed, but I didn't see anything that was talking about just bringing it all together.
Ill shut up now.
