[Edu-sig] Electronic assignment submission?

[Louis Bertrand]

Not necessarily a Python question (unless the solution is implemented in =
Python).

I'm looking for a system to hand in programming assignments =
electronically, and return them to the students (IMHO, a trickier =
problem). Web, email or other, ideally running on a freenix server =
(BSD).

It would be fun to write my own, and I've been looking at pulling mail =
attachments via IMAP and the MIME tools, or some sort of Web script.
But if it's already out there...

Any leads?

Thanks
