NFS has no coherency support anyway unless locking and rpc.lockd is
supported. Secondly there are methods (good methods too) of doing non-local
caches including cache leasing methods where a client caches data and the
server revokes the cache grant when the data changes. NFS v2 is not
a good file protocol anyway
