Steve, I just came across an old article by Jonathon Kehayias about Event Notifications (http://www.sqlservercentral.com/articles/Event+Notifications/68831/). IMHO, his seems to cover pretty much everything mine does, and a bit more, albeit from a different angle (and that may be what you want).

If what I've submitted isn't what you're looking for, I'd like to revisit it, incorporating aspects of my SQL Saturday lecture, specifically capturing changes to a table and multi-server implementations. That will take a couple more weeks, as I'm on the hook for a presentation for my local User Group next week.
