I also agree that this is a difficult part.  However, in the way I've
set up my prototype, this itself isn't actually a problem, as the
registering of events of organized slightly differently.

Yes.

Well, I think I've done things a little differently.  Allow me to wait
until I have something to show, though, before I elaborate.

By the way, I've tentatively named my prototype class and the associated
components 'notify.'  Someone--I don't remember who--pointed out earlier
that the name 'demultiplexor' is fairly awful, and suggested that new
name instead.  I like it.  :)
