This will be done by baboon, and it doesn't need "typed and scoped" event
channels.

This is done via GOAD already, and ... .

You don't want to broadcast server or document activation requests,
because broadcast implies zero or more listeners, and therefore no
guarantee that the request will be handled.

You don't need a generic message service; using application-specific
interfaces will prove more flexible, and you will still be able to invoke
things dynamically. Trying to genericize messaging winds up just adding a
bloat layer on top of CORBA, which already does the "send message, get
response" thing in a generic and dynamic way.
