What are the implementations of something similar to torrage.com torrent-hosting produced in Python?

Two modules running a Bit-torrent server, and uses Twisted like a client to coordinate control-message passing, and progress monitoring.

Ought to be simple to prototype in Django.
Seems like couple of lines of logic.
