I wrote a reply this morning, but it doesn't seem to have made it to the
list. Hopefully I'm not repeating myself...

I use a small Ruby module that I mix in to code that I want to be able
to "publish" an event. I setup my subscribers manually at run time (e.g.
within a controller action) and find it works really well.

Search this page for "Publisher" and you'll find it. It's really simple,
and is easy to work with.
