SiteConfig.pm is very simple. Here is an example:
package SiteConfig;

use strict;

use Exporter;

our $c;

@SiteConfig::ISA       = qw(Exporter);
@SiteConfig::EXPORT_OK = qw($c);

$c->{dbname}          = 'somedb';
$c->{dbserver}        = 'somehost';
$c->{dbuser}          = 'someuser';
$c->{dbpass}          = 'somepass';

$c->{site_name}       = 'Some Plain Text Name';

$c->{domain}          = 'some-domain.com';

#... and a bunch more ...

Then the other various modules say stuff like: use SiteConfig qw($c); So what would need to happen is that SiteConfig would have to export a "$c" that is appropriate for the current request (based on some way to determine which of four domains it's serving). That doesn't even seem possible (to export something different at run-time when it's loaded when mod_perl starts). I think we'd have to change the interface from Exporter to a function or method call (in every one of our modules). There is also one "quick access" method inside SiteConfig.pm that allows you to grab any value w/out importing $c:
sub param {
    return $c->{(shift)};
}

That one seems like it would be easy to modify to return the appropriate value, if only I knew some reliable way to determine from which domain the request was coming.
