Yes shot in the dark and I dunno exactly how it would be implemented. However with the release of google talk, theres a jabber server for everybody to use. Just a brain fart I had, it would be cool if its possible.
JWChat was written using AJAX technology it relies on JavaScript and HTML at the client-side only. It supports basic jabber instant messaging, roster management and groupchats based on the MUC protocol.
So lets support the open source people and make this hack a reality. I know I would install it for sure.
