What do I look for in a shared Python host?

[walterbyrd]

For example:

- If I want to use Django, I need either FastCGI or Apache
2.X/mod_python 3.x

- if I want to use TurboGears, I need Python 2.4: not 2.3 and not 2.5

- I have just learned that some hosters have T&Cs that forbid long
running processes. I am not sure exactly what that means. Except I
understand it can be a problem if using Cherrypy/TurboGears

- I have read that mod_python before 3.x can be difficult

What other "gotchas" would I look for?
