Thanks for submitting this example.  My first reaction is that an active
element, from an XP perspective, is an ongoing message exchange.  That view
would characterize an active element as one (or more?) end-point for 
sending and receiving XP messages (a session?).  The exchange pattern
could be characterized as an abstract version of send/receive.

All that aside, it seems as though you have some very interesting use cases
in mind.  Would you mind sharing those in more detail?  As XP takes shape, 
compelling use cases (*specific* examples of required exchanges) will be 
invaluable, and if they are deemed in scope might become a subset of the
