XMPP and user registration

[lp]

hi all

after reading the GAE XMPP API i cant find what i am looking for.

i require my server to register a user with a third party XMPP server.

however i cant see any mechanism of achieving this with/out the GAE XMPP API.

Problem 1.
there is no connection/authentication to external XMPP server in API.
Problem 2.
3rd party XMPP libraries are using TCP sockets will not work in GAE.
 
Question.
How can i register a user from a GAE application?

thanks
