Maybe we could use the same file, NFS mounted.

This would, of course, require that only one nmbd would have or need write
access at a given time.  Maybe asimple patch to the code that basically
shuts off updates to the database file for one of the failovers as long as a
"heartbeat" signal is detected on the primary file could work.  The
heartbeat could be something like a netbios name that would be updated every
30 seconds.  If the update failed, the secondary failover would start using
its own database file.
