Stef,
Thanks for your input/reassurance.
Vassili Bykov has a nice blog enty (Nov 2005) on announcements, and after skimming that, I have a much better sense (hopefully a correct one<g>) for announcements. Given that #trigger:with: can carry arbitrary information, it seems that announcements are a smaller change relative to events than events were to depencies of the MVC era - I'm still trying to forget about the latter.
Thanks!
Bill

I do not think so.
Announcement is nice because you manipulate objects.
