We love to revamp! Created a set of listener interfaces which are used

with distributed objects rather than having a single handleEvent() by
which all subscribers are forced to hear about all events. Now one
subscribes separately and then adds onesself as any of a few types of
listener once they have access to the subscribed object reference.
