PYTHorrent
This is a BitTorrent client written entirely in Python so that it can be
easily used for experiments. It is a fully working BitTorrent client so
you can use it below as an example. There is no intelligence in this
such as getting rarest peice first. Everything is random.
It doesn't use thread
or multiprocessing
as it's designed to be
used for experiments, and I don't know how someone may want to use it,
while also making it impractical for general use, but I'd like to
eventually support the most common schemes such as DHT, Magnet URLs, PHE
tDP, and UPnP so it is possible to accept incoming connections.
