alternatives to mod python

[snacktime]

I'm looking for a simple async ssl http server that can accept http
POST requests.  Performance is an issue, which is why I'm currently
using mod python.  I don't really want to require installing apache
and mod python though if I can help it, since this is software that
will be distributed to end users.

Anyone have any suggestions?  The only other thing I looked at was
twisted, which I'm still evaluating.
