// The XmppProxy is a shim interface that allows a class from layers above
// the protocol to insert custom logic for dispatching the XMPP requests
// necessary for creating a jingle connection.
//
// The primary motivator for this is to allow libjingle to be sandboxed in the
// client by proxying the XMPP requests up through javascript into a
// javascript-based XMPP connection back into the GoogleTalk network. It's
// essentially a clean hack.
