1. If you use RelStorage instead of ZEO, you should be able to use
database-specific replication capabilities.

2. Zope Corporation sells ZRS, which provides master/slave replication
for ZEO.

3. Christian Theune has been working on an interesting solution called
ZEO RAID. http://pypi.python.org/pypi/gocept.zeoraid
