Ok, I think I grok this now and it makes sense.  I've implemented the
PythonInterpPerDirectory On for each httpd.conf section that I'm running.
And it works like what I initially, but incorrectly, thought would happen.

I've read the section 4.1 Multiple Interperters and 5.4.4
PythonInterPerDirectory.  Will the pitfalls of URI translation impact my use
of sessions?  It looks as if I was trying to intertwine my app tightly with
the Apache request flow I might get some unintended effects but since I
don't think that is what I am after should I be ok?

Also, If I wanted to hide the .py extensions and I don't want to use the
PythonInterPerDirectory, I would most likely need to implement some apache
rewrite rules to do something like
/foo -> /foo/foo.py
/foo/bar -> foo/bar/bar.py



p.s. I am starting to write up an FAQ entry for this.  Do you think it
should go in Section 2.  Problems Running or another section?
