Cool.

True, although the Zope2 instance-creation scripts will probably become 
setuptools console scripts, which means that things will likely need to get 
shuffled around a bit from how things are now regardless and old hands will be 
baffled anyway.

repoze.zope2 needs the libraries, but doesn't need the stock Zope instance 
creation scripts (repoze.zope2's may actually conflict name-wise with those from 
"stock" Zope 2).  I'll see if I can figure out a way that repoze.zope2 can just 
use stock zope2 instance-creation scripts so making a different meta-egg that 
includes just instance creation stuff isn't as attractive.

Alright.

I'm excited about this. ;-)
