What vision is this? I don't think anybody has been proposing this 
vision. I'm not sure how any such visions relate to this discussion anyway.

One question: Who will pay for all this work? Given lots and lots of 
free programmers that will do all this development, this can happen. I 
don't see these resources, though. :)

So, we usually don't have that luxury. People have real projects in 
production and we want to start using Zope 3. One main route open to us 
maintaining existing applications is one of gradual evolution.

Of course the other alternative is to forget about evolving towards Zope 
3 at all and Zope 2 just going its own way, but I don't think anybody 
wants that, right?
