I suspect that finding a way to run your own is going to be easier
than inventing a new way to debug perl.  Can you tell us anything
about the barriers to running your own server?  We might be able to
suggest something.

You need a console attached, so I don't think so.  You could look at
what others have done with trying to debug forked programs, but
daemons like apache try pretty hard to detach from everything.

If I were going to try to do this, I'd probably start with
http://search.cpan.org/dist/Devel-ebug/ and see if it can be hacked to
work as a remote debugger for mod_perl.
