Chris & Randal--

That's right: I'm building it in Perl myself.  The database size is
actually quite small, but it's still mission-critical.  

Basically, it's a large stack of tiny little flatfiles.  If I could
write a script (called by cron) to look for all files that have
changed, and then deliver them to someplace across the net - well,
that'd be perfect.

-kari.
