[other great examples of this capability snipped]

You could call these "ChangeBrains". It's got a bit of alliteration to it :)

After reading Steve Alexander's message this morning, I started thinking
about how the Portal capabilities could be refactored into one or more
Specialists. This feature is also a very neat way for people to set up their
review policies for the Portal.

I'll send a message with more detail about my thoughts on a Portal
Specialist over on the zope-ptk list. I just wanted to chime in and say that
I agree that ChangeBrains (or whatever) are a Really Useful Thing.
