I've got a prototype of that in my latest SubFire "demo" (not yet released, my work in progress framework for SubFire 2). Basically, it shows a list of Now Playing, and when you click one (that isn't yourself), it starts 'following' that user. Every time the song from that user/player combination changes, the new song gets queued up in your own playing. Not perfectly simultaneous, of course, but the best I could do with the API as it is. The person you're following doesn't need to be using SubFire.
Proper multi-casting and near real-time sync would need something deeper on the server, of course.
