Dig a bit deeper into http://developers.facebook.com/docs/chat/. There are a number of XMPP and related APIs for Java, C#, iOS, and Android alike to be found on the web - or you can base such work on the libpurple API from Pidgin (http://www.pidgin.im/). It would behoove you to become familiar with XMPP concepts.
