	In LMFS there are permission bits for reaping and deleting.  There are
	no equivalent protections in NFS.

    Symbolics could simulate them by creating an auxiliary property list
    file (I think Macintoshes do something similar when they use Unix file
    systems, to simulate the resource fork of a Macintosh file).

But he would still lose if someone used GNUEmacs (which also reaps files
based on a per-user setting).  

My point was that if you're using NFS you're probably trying to
interoperate with Unix, not just use it as a place to hold bits.  In
that case, you are pretty much stuck with Unix's limitations.  If you
don't need the Unix interoperability, then creating a LMFS partition is
the solution.

    This would also permit you to implement the user-definable file
    properties if you wanted.
