recently i've come across project which develops open source browser based XMPP chat, they also have 'mini' version for chat widget one can embed on any site, you can find it here: https://mini.jappix.com/

I would see it attractive to focus only on server side integration of xmpp server and drupal and take advantage of very actively developed front end widget like jappix
