Obviously, I'm in favor of this.  I fear though that this will cause me
a lot of pain.  I'm in the middle of a bit of a geddon on the jim-adapter
branch.  The valuable work you propose is probably going to make my merge
a lot harder.  I hope to be ready to merge by branch in a couple of weeks,
but it's been hard finding time to work on this lately, so I can't
promise.

I can think of 2 ways to reduce my pain:

- Hold of on this work until I merge by branch.

- Do this work on my branch.

The second approach probably makes more sense.

Either of these have the risk that I'll never merge my
branch, but I'm confident that I'll be able to merge well
before May 1.

It would be great to focus on doing whatever is necessary to
avoid including zope.app in Zope 2.  If you could do this,
I think we could stop using zpkg for Zope 2 even if we don't
manage to use eggs in time.
