[Twisted-Python] Noob alert - Looking for a framework for creating a long polling service

There is a project built on top of Twisted that does exactly this,
called Orbited (http://orbited.org/). It works, and I use it for
internal real-time stats web pages. The one caveat I have with it is
that it recently appears to be somewhat inactive - though I use it so
much I might fork it and continue development ;-)

A good article showing you how to use Orbited is:
http://cometdaily.com/2008/10/10/scalable-real-time-web-architecture-part-2-a-live-graph-with-orbited-morbidq-and-jsio/

Other articles are featured on the orbited site.

If you're looking for a scalable, long-polling queue broadcaster *in
general*, I highly suggest nginx_http_push - an addon module for the
popular C-based asynchronous web server nginx
(http://pushmodule.slact.net/).

Start with Orbited though, and see where it takes you ;-)

Cheers,
Reza
