I wrote a c+tcl module for Jabber. It turns AOLserver into a Jabber client if you wish. The C module is very simple: it exposes every message to the tcl api, calling a pre-defines tcl procedure. You can set this procedure to do anything you like. The tcl module defines this procedure, and also includes a keep-connected procedure that automatically connects on server startup, and re-connects if either the thread dies, or the Jabber server dies. Also included is a method of using Rob Mayoff's threadpool module.
Currently this module is available at:
