I don't know about Samba, but Jim Fulton warns against _accessing_
Data.fs over NFS. It is a surefire way of corrupting it.

About sharing the Data.fs between multiple Zope processes: Don't do it,
it doesn't work. The Data.fs file is locked by the Zope process using it
for a reason.

For load balancing like this yuo will have to go with either ZEO, or
some form of XML-RPC based load balancing (ie. write your own).
