It is one of the EventBridge implementations, and as such is used in
two places in Cayenne:
1. cross-VM server cache notifications.
2. client commit notifications in 3-tier setup.
Actually I wrote XMPP version of the event bridge specifically for
case (2), as unlike other Cayenne "bridges" it provides extra
*presence* information, so one can write an app on top of XMPP server
to watch who is online at any given time, or send an IM message to
all connected Cayenne clients, etc. I see lots of possibilities here...
