working on a real time application using django

I have been researching this for a day or two. I am working on a real time application (a chat and a video chat). I am using django/apache combination which I understand is not suitable for this (at least the apache part).

In this regard I found several links from within stackoverflow such as http://www.skitoy.com/p/django-tornado-chat/305 and some comparisons such as the one at http://nichol.as/asynchronous-servers-in-python

My question is. Can someone who has worked on django real time application let me know 开发者_开发知识库what framework I should use. It seems that I can use either django on tornado or use django with twisted framework. I am new to real time application and just need pointers so I can save some time.

Some more tips here from people who've done similar:
