Thanks for picking those up. The suggestions are pretty much like what
we've been following: split out the non-ZMI parts from zope.app.* into
zope.* packages.

WRT the ZODB issues: I've started working on a 'touch' tool for ZODB
that analyzes (pickle-based) storages for class references which are
missing in your code base and (if all class references exist) can touch
all objects that reference classes from indirect imports.

Just a note: Martijn and I are currently trying to stabilize the zope.*
trunks to get releases out. I think we should try to avoid stepping on
each others toes here.
