I'll edit http://us.pycon.org/TX2007/WebFrameworksPanel as I update things, but here's the proposal I submitted:

Frameworks:

• Zope (?)
• CherryPy (Robert Brewer)
• TurboGears (Kevin Dangoor?)
• Django (Adrian Holovarty?)
• Pylons (Ben Bangert?
• Quixote (Neil?)
• Twisted web (?)
• web.py (Aaron Swartz?)

2 minute presentation by each representative, introducing:

• point of framework;
• short example
• guess at user base
• size of developer community

Followup questions:

• When did the framework come into existence and what problem was it created to solve?
• Why did the frameworks that existed at the time not meet your particular needs?
• What are its strengths and maturity level? What is it ideal to use for?
• What wouldn't you use it for? why not?
• What frameworks are related?
• What are your future directions?
• How do you feel about WSGI, and what benefits (if any) do you think it brings?
• Do you use an O/R mapping (SQLObject/SQLAlchemy), and if so, what benefits do you think it gives you? Any negatives?
• What template language(s) do you favor/support?
• How well do you support AJAX?
• What sort of testing infrastructure do you use/support?

I'll have a chat server or a Web site where people can ask followup questions, if the Internet connectivity is sufficient (it wasn't, last year!) Otherwise, I'll open the floor up to questions towards the end.
