It is possible to "mount" a second storage at a given point within the
main storage used by the database:  the standard zope.conf, for
instance, sets this up for the session data::

 <zodb_db temporary>
    # Temporary storage database (for sessions)
    <temporarystorage>
      name temporary storage for sessioning
    </temporarystorage>
    mount-point /temp_folder
    container-class Products.TemporaryFolder.TemporaryContainer
 </zodb_db>

You can do the same thing in your two "special" clients, setting up a
mount for the "private" storage.

One caveat is that you will have to add a "mount point" object (an
instance of 'Products.ZODBMountPoint.MountedObject.MountedObject') in
the main part of your database at the path pointed to by 'mount-point'
in the configuration.  The other clients will see the "empty" mount
point, but won't be able to traverse into it, because they won't be
configured with the stanza that actually creates the mount.

HTH,
