Thanks for the clarification. So stateless _uses_ state but just doesn't
have it bound to the session?

If that's true, is there a deeper sense behind StatelessSession not

IOW, should I reasonably be able to cook up a
"SomewhatStatelessSessionWithAgendaSupport", or would I end up with a
half-arsed StatefulSession ?
