Well this is the big question. Does he want all or some?

If you want all the user info then yes accessing a remote database would be your answer.

To do this just create 2 Database handles:

my $dbh = DBI->connect('DBI:mysql:database=dbname;host=localhost','use
+r','pass');
my $dbh_user DBI->connect('DBI:mysql:database=userdb;host=remote','use
+r','pass');

Even better use Class::DBI. You'll be able to hide all the ugliness of having 2 separate databases. Just create 2 unique DBI classes to inherit from.
