Note that Shane developed a sharding solution a year ago with me. It provides 
container-level partitioning.

http://svn.zope.org/z3c.sharding/trunk

This in combination with the encryption work that we did for the ZODB makes 
the ZODB actually be a lot more advanced than some of the new comers.

I am very intrigued now to setup an EC2 cluster and install a z3c.sharding 
based solution demonstrating 100M users with some data. Mmmh...
