thanks for the prompt replies.  to recap, i have
-Berkeley DB
-External Mount
-something that i'm not too sure of :)

as i see it, i can use External mount to mount berkeley Db.  that will then 
give me a nonundo, nonversioning db.. right?

if i use FileStorage with ExternalMount, it'll be just another ZODB.  i hope 
i'm right.

if i want to use it across ZEO Clients, i *must* use ZEO.ClientStorage.  
correct me if i'm wrong, please.

to test a simple setup, i tried FileStorage with External Mount.  and i 
encountered a little problem.  here's what i have
-ExternalMount
-External Method[1]

when i tried adding an ExternalMount, i got this[2] traceback.  help?

p/s - what about storing CoreSessionTracking data in RDB?
--
[1]
---ExtDB.py

import ZODB
from ZODB.FileStorage import FileStorage
 
def createDB():
return ZODB.DB(FileStorage('/home/kdie/Zope/var/ext.fs')) 

[2]
 NameError
  
  Sorry, a Zope error occurred.

And a third message...

The SessionStorage.py file that ships with CoreSessionTracking is a storage
of its own that's RAM based.  It's based on an (as yet unreleased)
"packless" Berkeley storage implementation that Jim Fulton created.

I'd really like to get the Berkeley version of this architecture released,
because it's also nonundoing and doesn't require any packing unless your
database has circular references.  We've been in a sort of limbo in
releasing it because I think we wanted to release a "full" implementation
(one which supported undo and versioning), but I'm going to see if I can get
the packless piece onto Zope.org without waiting for the rest of it.
