Well, yeah, you'd have to implement the low-level part of peer-to-peer.
But the HTTP infrastructure is usually enough for that: broadcast by
performing a GET /?file=name to say you have a file called "name"
and the nameing service turns out to be composed of 302 redirects.

You have insulted the prophet: your punishment shall be cruel indeed!
Of course HTTP supports resuming transfer. SimpleHTTPServer doesn't
though. I don't think it should be hard to add, though.

An advantage of HTTP is that it will be possible to use the protocol
with clients not written in Python. If what he wants is simple file
exchange, there is no reason to be limited to Python at the protocol
