Well yes, but my stated aim was to get somethign which worked in Zope 2, 
Zope 3 and outside of Zope. I see no reason to have three different 
versions of ZPT which all have to be independently supported and optimised.

Ah, the "zope" package problem again :-/
What did the Zope 3 people decide to do with that and the clash with the 
Zope package in Zope 2?

I think it is, since if it works outside of Zope 3, why should it not 
work in Zope 2? ;-)
