Right now, MobileFrontend expects the mobile-version URL of a Mediawiki install to follow this convention:
$hostParts = explode( '.', $parsedUrl['host'] );
$parsedUrl['host'] = $hostParts[0] . $wgMobileDomain . $hostParts[1] . '.' . $hostParts[2];
eg, en.m.wikipedia.org. This should not be a requirement, but rather should be user definable for greater flexibility - either as a standalone subdomain, completely different domain, different path with the same domain as the non-mobile version, or even potentially as a query string.
