The Django orbit integration methods I've seen in quick google searches don't seem to carry Django abstractions, like "request.user" with them. "request.user" is particularly important, since I am not going to (potentially incorrectly) re-implement session handling (this sounds like it could cause bad security bugs).
Alternatively, should I use a different server? I'd prefer to use stable, mature, popular software, that will be maintained and improved. Orbit and Django seem to be qualified.
If you're looking to "integrate Django and Orbited", you might have a look here: http://github.com/clemesha/hotdot which is a very complete (but not yet polished) example of what I think you are looking for.
In particular, the example includes Authentication using Django models from the Orbited process (more specifically, Twisted Cred + Django models), as well as filtering and modifying of in-transit Orbited messages. In the example you'll find that you basically get the "request.user" object because the "request.user" object can be accessed by the cookie that Django sets + database calls using django.contrib.sessions.models.Session model object.
