Awesome email, Chris -- thanks for sharing!

In particular, I am tantalized by the paragraph above ;-) As I alluded 
in a previous post, this has been a very painful point for myself an 
other developers with whom I have worked. For one client, we used the 
CMFPlone.MigrationTool on a Zope2/Plone project where content addition 
was occurring throughout the development phase. I found the tool 
cumbersome and the whole process most painful and distasteful.

Do you employ an analogous tool or elegant manual approach for z3 
projects? If you have no tool, have you guys compiled a best practices 
doc (informal or otherwise) whereby those of us inexperienced in these 
particulars could benefit?
