Upgrade Dingaling to meet new googletalk spec upgrade your client if you have issues.
codecs need more work...

Expose events into javascript so you can create and fire events and 
and pick up chat events with chat-enabled clients like googletalk
EXAMPLE:

session.answer();

e = new Event("custom", "JS::Custom");
e.addHeader("subject", "cool");
e.addBody("hello this is a test");
e.fire;

while(session.ready()) {
    session.execute("sleep", "1000");
    event = session.getEvent();
    if (event) {
      str = event.serialize(); // or ("xml")
      console_log("debug", "Dump Event:\n" + str + "\n");


        e = new Event("custom", "JS::Chat");
        e.addHeader("works", "yes");
        e.addBody("you said: " + event.getBody());
        session.sendEvent(e);
      event.destroy();
    }
}
