+0  We're really not sure what the story here is yet... trying to sort
things out.

terrific.

great.

great.

Interesting, but definitely needs more thought.

Indeed.  Zope's eggification story needs to be straightened out.  We see
some of this with Jim's proposals for Zope 3.  I'm inclined to watch the
discussion for Zope 3 and hopefully see a good solution unfold (of
course I won't be afraid to share my opinion).  My suspicion is that
Zope 2's eggification story will be very similar (best case scenario:
identical) to Zope 3's eggification story.  So this is one place where I
say let Zope 3 work it out first :)

Well... constructive comments at least...
