Hi Paul,
Funny you should ask! I'm doing pretty much the same thing you're
planning to do. I'm hoping to get permission to open-source my code in the
next week or so; I'll drop you a line when I do. The script recorder
certainly won't be finished then, but any help anyone wanted to give would
be most appreciated.
BTW, I think I've come up with a way to figure these interfaces out.
Unfortunately, it doesn't involve ruby. 
I'm going to put together an
HTML page with all the controls I care about, then run it through a python
program that will output all the connection points for those controls. Then
I'll use the discovered interfaces in the ruby-based script recorder.
Python's COM support includes low-level stuff like QueryInterface that I
haven't been able to figure out with WIN32OLE. Any port in a storm, I
guess...

Will, can I ask what you aredoing with these interfaces? Im working on
a new version of some code that we use to test web applications via
IEs OLE interface and DOM.
One of the things Im hoping to do is a script recorder, and these
events would be essential in letting me recoed a users actions
Thanks
