OK, some initial, fuzzy comments:

You are thinking about things like TTW development and such? Because I
see that as add-on products of different kinds. Like cpsskins to
develop the look, and some sort of persistent schemas combined with
some sort of aspect-oriented classes. ;-)

If there is some sort of real "core" thingy that you lose going from
Zope2 to Zope3 I must have missed it. :-p

This overwhelms my complexity sensor. :-)

I like the vision of Zope2 becoming a set of extra packages you
install for Zope3, to get backwards compatibility. Maybe this is the
same as what you call Zope 5, maybe not.

This is definitely true...
