That's perfectly acceptable, just try not to start/shut down all the
clients at the same time if you do so.  Our locking mechanism isn't
perfect, and NFS's caching mechanism causes it to fail when large
numbers of NFS clients access the buffers at the same time (which will
only happen if all boxes start/shutdown at once, in reality.)
