Here is the first usable version on serendiPd (formerly known as xp4pd). It is a patch that allows multiple people to edit a shared patch in realtime over any network.

Its still quite buggy and not feature complete. For example, locking is absent so things can go crazy pretty easily when mutiple people try to edit at the same time. But it works and its a crazy experience to watch someone write a patch on your computer from anywhere else in the world.
