// Basic XMPP bot example for HipChat using node.js

You'd have to add the password element to the room join presence as shown in the spec: http://xmpp.org/extensions/xep-0045.html#enter-pw

Lines #44-46 at the time of this comment:

  setInterval(function() {
    cl.send(' ');
  }, 30000);

crashes the app when it cl.send(' '); I ended up replacing it with cl.send(new xmpp.Message({}));, which still threw an error, but at least it was handleable.
