In "classic" NFS this isn't really possible.  NFS is stateless, so on
the server you can only see momentary reads and writes from files, you
cannot see if a file is, say, opened by a client but the client is not
reading and writing to it at that moment.

Modern NFS is a little bit different.  I think NFSv4 maintains more
state on the server, and also you've got things like file locking, so
maybe it is possible to get more information out in those cases.
Someone else who knows about NFSv4 will have to answer that more
definitively though.
