You might actually consider doing your report generation from a different
viewpoint...use a web crawling tool, or even the perl GET module to
simply run through all the web pages you want to gather reports on
and grab the data from them that way.  It'll hammer your webserver a
bit harder as you do the run, because you'll be sequentially generating
web pages for everything going into your report, but it means you can
generate your reports anywhere, without needing access to the static
html files on disk.  It also means that you won't have to make any
modifications to your 14all setup.

Just a thought...
