I take it you're not a Perl developer.  By using LWP I
wouldn't be skipping any of the application's edits, I
wouldn't be violating any referential integrity rules,
and I shouldn't end up with duplicate anything - as I
wouldn't be hitting the database directly.  LWP is a
"set of Perl modules which provides a simple and
consistent application programming interface (API) to
the World-Wide-Web".  In otherwords, I'd still be
using the application, it would just be a Perl program
that was stepping through the screens.  Not me, or one
of my staff.
