It's theoretically possible, but almost certainly a bad idea. Do you
already have a large mod_python-using codebase?
If not, Twisted includes HTTP support for a reason. Just use it :). To
communicate with your apache server, use mod_proxy or something similar
to just relay requests to the Twisted web server.
If you do have a large mod_python-using application already and you are
trying to get it to talk to Twisted, you probably want to continue to
use the mod_python execution model rather than spin up the twisted event
loop and switch back and forth: while it's possible if you really need
it, a better architectural strategy in the average case (to avoid odd
interactions between the assumptions mod_python has about its
environment and the assumptions twisted has about its) would be to use
Twisted's XMLRPC support and talk to it using a blocking XMLRPC library
from your mod_python scripts.
