Thanks.  I skimmed through this (too quickly).

The general idea of separating event sources and sinks is already
handled by the CORBA event stuff.  Basically our event manager will be
what CORBA calls an event channel.  Other objects can register event
sources and sinks with the channel without knowledge of who else is
connected.

The spec also seems to include lots of predefined event types.  This
looks pretty interesting.

There's also a lot more stuff in there that I didn't read.  It is
quite large.  If somebody familiar with it would like to give an
overview of the scope of the thing, I'd appreciate it.  Otherwise I'll
just add it to my growing list of stuff I should read sometime.
