Thanks Jim,
I had gotten to the following point (although you have now shown
me a better way to get there, I was using FileStorage):

print f1[0].values()[1].__getitem__
bound method BuddyFolder.__getitem__ of
buddydemo.buddy.BuddyFolder object at 0x1377f30
I don't know what to make of the above without any context.
That's fine, because I don't really have time to study any specifics.
This is where I get stuck. Been going over the sources to figure out how
to iterate over these.
Understand that this has nothing to do with ZODB. Whatever
application objects you use provide whatever api they do
indepenent of ZODB.
...
I did notice since I did this, bin/runzope acts differently (on this
Zope/ZODB?).
Differently than what? In any case, I suggested that you use zopectl.
runzope is an internal implementation detail of zopectl.
I created a new instance in 121
and transferred all applications and the new instance works fine:
Robs-Laptop:~/Projects/Zope/Zope3/One2One rob$ cd ../121/
Robs-Laptop:~/Projects/Zope/Zope3/121 rob$ runzope
--

--
2006-10-27T14:45:57 INFO root Startup time: 9.072 sec real, 8.710 sec CPU
^C
But the old instance in One2One now just seem to test:
Robs-Laptop:~/Projects/Zope/Zope3/121 rob$ cd ../One2One/
Robs-Laptop:~/Projects/Zope/Zope3/One2One rob$ runzope

Robs-Laptop:~/Projects/Zope/Zope3/One2One rob$
Any idea what causes this?
No, I have no context to begin to understand it. I don't know what
121 and One2One are.

You're 2nd point, about using ZEO, is also very valid (I need to just
read my 'buddies' and send the
data down to a bunch of embedded Linux based controllers but the ZODB
will be locked).
I did notice since I did this, bin/runzope acts differently (on this
