OK, so what do we call them? Monkey patches? ;) To my mind, a "Product" adds functionality to Zope, it doesn't change some core behavior (thought there are products out there that do, like ZDebug). So I suggest we need a way to distinguish these types of hotfix-methodology based products. Or a subclass of Product... I can't think of a good name. Patch would again imply fixing something...
coreMods? flyingMods? (as in "on the fly") coreJimmies? (think east coast ice cream) pixieDust?
I was thinking of <something>Extension. Maybe coreExtension. I don't know, I'm terrible with names. The last five hampsters I had, I called Buddy. Now that I'm getting a puppy, I need to think of a name. Guess what? LOL. Tommy Innovation: The Best Way To Predict The Future ... Is To Create It.
