ACK. And there is nor reason why it shouldn't work. After all, if I have
10 spamd's running, it doesn't really (for the Bayes-DB as such) matter
if they run on the the very same host or on 10 different.

As always: Depends on the load and the available hardware;-)
File-locks-over-NFS are more expensive then for local filesystems
(additionally to the latency from the network).
If you encounter locking contention (even without NFS), switch to some
SQL-DB.
