Thanks for the typo-correction for the URL:

http://www.cs.bell-labs.com/who/dmr/tdvirus.pdf

is indeed the correct current place.  I heard from Duff
that he's content to have it visible.

The topic is somewhat off-topic for Plan 9, but not
by too much, because similar schemes remain plausible
in Plan 9 systems.  Among the small changes to recent
filesystems/protocols is the transmission and maintenance
of a last-modifier UID for files--one of the minor but
useful diagnostic tools that help.

Gwyn's correct, by the way, that AT&T Federal Systems
did do System V/MLS certified to B1 or B2 or so.
This was independent of the McIlroy and Reeds work,
though I'm certain there was consultation.
