Just curiosity - was wondering how many people actually use your server? Personally, I'm using subsonic for the Android client and the fact that I CAN set up different accounts for friends and such, but I know other people have different reasons and motivations.
I voted me + 1 or 2 others. I would invite more people to use my Subsonic server but my horrible upload bandwidth doesn't make it possible. So instead I have helped a few buddies set up their own subsonic servers
