MountedFileStorage lets you mount the root of the database through a
very "iffy" scheme that I don't think could be made reliable.  I'm sure
there's a right way to do it, but I think for now your best option is to
create a folder in the database you intend to mount, then move all
content into that folder.  That's how Wikis.fs is mounted.

Here's our external method:

# Define the Wiki database mounted database
import ZServer, ZODB, ZEO.ClientStorage
 
def wikidb():
    Storage=ZEO.ClientStorage.ClientStorage(
        ('10.0.11.1',2222),
        cache_size=50*1000*1000,
        max_disconnect_poll=40,
        min_disconnect_poll=1,
        storage='Wikis',
        )
    return ZODB.DB(Storage)

Been hacking kernels lately?  There's no hacking like kernel hacking. 
Bare metal.  Oh yeah. :-)
