if CGI scripts can't read notes, then it should be mod_cgi's job to
turn a bunch of notes into envs, preferably after the fork and
before the exec, so the parent process' environment doesn't get

Can't all these modules (your scripts, mod_ssl, etc) just use the
request object and/or Apache notes to communicate? That's exactly
what they're there for!
At least mod_perl can be told not to mess with the environment:
PerlSetupEnv

PERL5LIB=/usr/local/ssl-apache/perl-lib ; export PERL5LIB

But you can open your filehandles with open(), sysopen() or any of the

sh element; if you want your forums to share the rest of the site's
look, then you need to write templates for these things too. And
session management is spread among dozens of scripts, so you can't
easily make changes to the way it works.
The whole point of the iAct project is to have a system that works
*both* for thousands of static pages sharing a common look (in a modular
way, hence the reverse-include approach), and for "web-apps" with perl
and a database as the backend.
