You need some place to put the announcer. Depending on your
application either a custom session class or the root component might
be appropriate.

Yes, I've done this many times. Whenever an event happens you
initialize an announcement with the script of the evaluator. Anybody
interested is subscribed to this event and can add code to the script
to update itself.
