If you could write up your question with a little more detail on what you're looking for, what you plan to use it for, etc. then this would make a good question for an AskSlashdot. http://ask.slashdot.org

I think Plone will do what you're asking too. Plone is based on Zope (written in Python). http://plone.org

Anything I can think of off the top of my head though will need additional programming/customization to integrate it into PayPal. I assume you mean use PayPal's API so when a user tries to access, for instance, the Thom Hartmann archive section that the software checks to see if the user's subscription is current. In that regard, Plone is a good choice in that you can add functionality like that.

I'd be interested in what you find too.
