You can do that now (with Plone 4), but you won't get a Zope 2 instance with 
it (which is what we use recipe plone.recipe.zope2instance for). repoze.plone
(which has been deprecated since Plone was converted to eggs) and running 
Plone w/WSGI in general, has the luxury of not requiring Zope 2.

OK so you want to create a Plone libs tarball and package it as a .deb,
sounds good to me. I like the omelette hack too (why not just make
that an option for collective.recipe.omellette proper though, instead of forking?)

Note (as I explained to Erik, on IRC) my goals are somewhat different in that
I only really care about providing multi-platform installers for people to use,
to get more people using Plone. I'm not *as* interested in using the packages
myself (i.e. I don't have to run WebLion).
