I never used it with WO, but I wrote a Smack-based XMPP client for

targeted notifications of context changes. Pretty cool.
Was this instead of, or in addition to, the use of Hessian (which I
thought you were using, perhaps that it was being used for the
actual data transfers and Smack just for notifications)?
This is separate from Hessian part. Hessian-over-HTTP is the main
communication channel used by the clients to interact with Cayenne
server (pull model). Update notifications use an (optional) separate
peer-to-peer channel (push model). It is pluggable too - we provide
implementations based on XMPP (firewall friendly), JavaGroups (very
simple configuration, but only works on a local subnet) and JMS.
