All the information in that article is geared for Zope 2.5 which had no
facility for using mounted databases from a config file... everything up
until "At this time you should be able to navigate to the
/session_storage folder..." in that article can be done by reconfiguring
ZEO using zeo.conf to serve a new storage, changing your ZEO clients'
zope.conf files to recognize the new storage and adding a "ZODB Mount
Point" from within the ZMI from one of the appservers.  The rest of it
is pretty simple. ;-)
Please, take a look in what I've done! Is that right? It works pretty 
fine here! :-)

If this is right, are there a desire for a how-to? I think I can write 
one, once it's pretty simple as you said.

    # ZEO client cache, in bytes
    cache-size 20MB
    # Uncomment to have a persistent disk cache
    #client zeo1
  </zeoclient>

<zodb_db temporary>
  mount-point /
  # ZODB cache, in number of objects
