This thing is impressive in its feature set. That it’s a self contained wad of python is doubly impressive. I (unsubstantiated) worry so much that there is just a litany of issues hiding in it, being such a broad multi protocol system. But on an internal protected network, huge for a group of friends to share stuff with.
The author has an impressive demo server with lots of good content too.
