Sounds pretty good idea.
I've been testing this announcer plugin for a while and most of it's
functionality is pretty ok. (I haven't looked code)
One feature that I'm missing is automatic "add me to watcher
automatically" for tickets. I mean that for example when I create custom
ticket query I could say that add me watcher to (these and) any future
tickets that matches my query.
