Nope, tho you have me interested.  I've been looking more at using
XML/RPC and tieing inter Jabber (I like Jabber, don't like SOAP, and
have little fondness for closed protocol stacks (AOL regularly
blocks/disconnects non-AOL servers from messaging AOL AIM users)).

TCP RTT is a killer.

IIRC (its been more than a year) one of the things that the Jabber
protocol allows for is persistent bi-directional connections.  AIR the
OSS source base doesn't support it, but its allowed in the spec and its
one of the primary performance gains from buying/using jabber.com's
commercial implementation.
