a second "unspoofable" uid with NFS

[drl at vuse.vanderbilt.edu]

Because the root userid is so powerful, the default behavior of NFS is
to change all references from root on a client computer to be from the
nobody user instead.  You can bypass this security but this is the
default.  Unfortunately, since this is the only "unspoofable" user id,
many files end up owned by root (to prevent NFS tampering) that would
not need to be owned by root in a not-NFS environment.

Is it possible to configure NFS to support a second userid switch so
that the files that don't need to be owned by root can be owned by this
second special ID?

Is this a reasonable thing to want to do?
