Yes, I am in the same situation.  It sounds from a user interface point
of view, that Zope can do Python embedding easily, so then the question
becomes whether this idea would be more efficient than Zope (in terms of
page generation, AND simplicity of deployment).

Well, I wanted to allow the editing of Python code blocks from within
the HTML editor (that would prevent any kind of autoindentation).

Cool!

I thought that the CGI variables could be directly translated into local
variables and accessed like that, or possibly just turned into a
dictionary called 'cgi'.

I think this would be a very nice feature as it would mean that ISPs
could grant CGI access to their users (provided their users are willing
to learn Python - and what language could be easier to learn?) without
raising any security concerns.

Yes.  We look into writing indentation modes for Emacs, and combining
HTML and Python modes in some way.

Peculiar, if the problem could be replicated then we could get whoever
wrote SimpleHTTP on the case.

Hopefully none if we execute the Python scripts in a "padded cell".

I look forward to taking a look.  Are you willing to release the code
under the GPL?

Ian.
