FWIW Fred Drake (PythonLabs/ZC) is working on zpkg: a packaging and 
dependency management tool, integrated with distutils.  I believe the 
intent is to propose this as a Python tool eventually (presumably with a 
less "z..."-like name?).  I know the immediate intent is to allow 
various different distributions of the Zope 3 code (including perhaps 
just the interface package for you all) to be distributed.

That description doesn't give it much justice, but this should begin to:

I believe Fred is still actively seeking feedback, and requests feedback 
and questions on zope3-dev at
