Okay, I seemed to have solved most of my problems. Only issue having now is
pysqlite2 doesn't like being called from threads seperate from the ones that
created it. It could be run as a deferred in this case since it does respond
pretty quick. But I am sure could solve this issue simply by changing to
mysql or postgresql. The solution was stupidly simple.

from twisted.application import strports, service
from twisted.web2 import static, server, http, wsgi, resource

import sys
sys.path.append("./myproject")
from django.core.handlers.wsgi import WSGIHandler
import os
os.environ['DJANGO_SETTINGS_MODULE'] = 'myproject.settings'

class toplevel(wsgi.WSGIResource):


    def child_media(self, ctx):
        return static.File("./myproject/media")


root = toplevel(WSGIHandler())
application = service.Application("web")
site = server.Site(root)
s = strports.service('tcp:8000', http.HTTPFactory(site))
s.setServiceParent(application)


It works fairly well, or would if I wasn't testing on windows. Before you
ask why windows. I have box I dual boot into and normally run secure shell
to, using ubuntu linux currently. Unfortunately my computer has sims 2 on
which my g/f has been playing religiously lately. So I am stuck using
windows at work for right now.
