The Twilight Report

I am looking for a web based Jabber/XMPP client application to sit on my web server. The jabber server itself is on the same physical machine, although it is a different IP address. Ajax is okay, but all data between the web browser and the web server would have to be over port 80 or 443 (https), so that it won't get blocked by people trying to access it at work. Ideally something easy to integrate with apache (a PHP application for example), but I'd also consider a mod_perl or Java servlet if it came down to that. Any one have any recomendations? Google search suggests a number of options, but I am not sure which would be best.
