I've taken a look at stepper and dug into the zope source again.  It looks like 
both are relying on a startup script akin to zopectl to marshal everything 
correctly.  I would rather not be using a startup script (besides I couldn't 
sort it out); this is what I have so far:

        from Zope.Startup import options, handlers
        opts = options.ZopeOptions()

unfortunately in the resulting options object, I'm not getting the stuff I need 
from the conf file, namely the ZODB storage stuff needed for ClientStorage.

The schema file that is being used by ZopeOptions is 
Zope/Startup/zopeschema.xml.  This only has a skeleton zodb_db section.  It 
looks like the meat & potatoes are in ZODB/component.xml, but I don't see how 
that is actually pulled in.

Any more ideas?

Have a look at the run.py file in Stepper:


It shows you how to parse zope.conf without having to start Zope up...

You may wish to wait for Stepper 1.3.0, though, which shows you how to
do this for both Zope 2.7 and Zope 2.8...
