Last I looked GAE's XMPP is limited to just sending <message/> stanzas to your application, and having the application respond with a reply <message/>. If you want to do anything more complicated with XMPP you have to use your own servers or server components on some other infrastructure. That said, you could still develop the REST interface on GAE, and have your own XMPP server component act as a "proxy" to the REST interface by marshaling incoming <iq/> request/responses to the REST interface. Running your own XMPP servers on cheap linux hosts and/or scaling server capacity with Rackspace or Amazon seems like a viable solution (with all your data load on GAE you can just use as many of the cheapest Amazon/Rackspace instances you need to maintain client connections).
I'd love to see "full" support for XMPP on GAE, but given XMPP's stateful nature I doubt we'll see it any time soon, if at all.
