I think the trick here is to get mod_perlite to the same status as
mod_php, i.e. be provided by cheap web hosts in a way mod_perl
isn't (because of the overhead of configuration on their part, and
lack of isolation from other customers' code).
Obviously no cheap web host will do this today since mod_perlite
doesn't exist yet. But if there something viable and a demand for it
maybe they will provide this kind of support for Perl by default the
same way they do for PHP.
Did that clear anything up?
