If I do a refactoring on existing Zope3 code I proable have to 
support backward compatibility on other z3 packages for a clean 
commit where all unit test will pass. If we merge the Zope2 
code into one trunk, we have to take care on this unit tests as
well. Or we will see broken unit tests in the future.

So future development will become pure XP programming. On 
Zope3 developer and one Zope2 developer for each commit ;-)

I think you are proposing to mix two totaly different framework
into one big trunk and the benefit will be in getting "Products"
back from Zope2 developers.

We are not in that state right now. We have a lot to do before 
we can take car on "Products". I thnink we have to do several 
refactorings before we can do such a joint venture.

No, we really need developer like Chris. But the organization
of a development trunk has nothing to do with that.
