- Zope Corp sells ZRS (http://www.zope.com/products/zope_replication_services.html 
)

- Shane Hathaway's RelStorage (http://wiki.zope.org/ZODB/RelStorage)  
promises to accomplish some of the same sort of thing with (for  
instance) Postgres tools though the page I listed says that this is  
untested.

- Christian Theune is working on ZEO RAID: http://pypi.python.org/pypi/gocept.zeoraid/dev
