Upon reading your requirements, it appears that you need some sort of
Reverse HTTP or a COMET-style communication mechanism. If you want to
use Twisted primarily (though to do r-HTTP or COMET, you don't /need/
Twisted), you can give orbited (http://orbited.org/) a shot or you
could roll out your own. You might also be interested in the "ptth"
proposal ;)

I would recommend that you look at Eventlet (based on greenlet:
http://pypi.python.org/pypi/greenlet).

http://wiki.secondlife.com/wiki/Eventlet (prefer using the Mercurial
repo version).

And there is a good end-to-end example of a chat server:
http://www.evilchuck.com/2008/02/toy-chat-server-with-eventlet-and-mulib.html
(You might have to make some modifications, just in case the example
code is incompatible with eventlet 0.8.11-pre)

If you like what you see, please join the eventlet mailing list and
you will definitely get help.

Thanks,
