This should provide the beginnings of a migration path for current Zope 2 developers and hopefully actually accelerate the adoption and use of Zope 3 (since Z2 developers will now be able to take advantage of Z3 technologies in Z2 applications).
It was a pleasure to meet and work with so many of the superstars of the Zope community in the same room - I hope to be able to do it again in the future!
