What do you mean by "handshaking"?
Probably the roster synch, and particularly TLS/SASL/session/bind
setup. Aside from that, the rest of XMPP doesn't use a lot of
waited-for round-trips.
FWIW, my client implementation, being part of the rest of my
low-bandwidth email library, has low-bandwidth, high-latency
emulation, which can be useful for this sort of thing. It's not a
complete XMPP implementation, though it's getting there. It also does
debug traces, of course.
I'd be interested in exchanging notes, long thin connections with
XMPP is something I've been meaning to look into in more detail.
