code.google.com/p/django-chat/ — demo works well, but code last updated in 2008, so possibly unmaintained
code.google.com/p/django-jchat/ — uses jQuery. Maintained code with good blog posts explaining how it works
code.google.com/p/django-jqchat/ — again, uses jQuery. Maintained code. Has demo that works well.
