Hi Jeff,

last time I promised I would be more responsive to your mails, so here you 
go. :-)

First of all, let me say that I have no system in production yet, which uses 
eggs. I think only Lovely Systems and Zope Corp. do; and maybe some smaller 
applications. So I would not worry about not being up-to-date. In fact, the 
last stable release is still 3.3.1, which tells the story of the big Zope 3 
tree.

That said, have you seen my Zope 3.4.0b2 announcement _[1]? It was the first 
public announcement making people aware that eggs are really happening. I 
purposefully did not say that Zope 3.4 will be the last tarball release, 
because (a) I think we cannot abandon people that quickly and (b) it is now 
really easy to create a new tarball release thanks to a couple of scripts I 
wrote.

In the Zope 3.4.0b2 announcement I also sketched out two ways projects can be 
built using eggs, buildout and recipes. That said, writing a comprehensive 
migration document is still one of the tasks that need to be done. I was 
really hoping that the community would step up in writing one. I think that 
Darryl's response to your mail is a great start actually. It could easily be 
used as a starting point.
