python based push frameworks

This talk is about the web based pushing of data (as done by gmail or facebook) to send live notifications to user in real-time.

This is one of the very burning topic of modern day web development, and I'll present the way to get this done via Python and Django.

The talk that I want to present is on the reverse-ajax/comet implementations available in python, I used one such technology in http://soch.la for server push and another in http://yackit.com.

The main topics that I am looking to cover are:

• What is comet/reverse-ajax?
• Available options. (prominent once - nodeJS/Twisted/websockets/flash)
• Available pythonic options.
• Comparison between nodeJS and Twisted.
• Minimal sample application via Twisted + Django.

I am a python hobbist, working in web industry from 4-5 years in python. I've worked at companies like Belzabar Software and Interra Systems, but recently I've moved on to start a company to make http://soch.la along with a couple of guys. http://tunesdiary.com is another product that I working on these days.
