there have been some number of recent references to
gnosis/keykos from a security perspective. however within
the contenxt of utility computing and time sharing service
bureaus and stuff like:
http://www.infoworld.com/article/03/10/01/HNsunsema_1.html

when I was asked to perform due diligence on gnosis was that the fine
grain capabiilty wasn't done so much for security isolation (that was
also needed in an open time-sharing service bureau operation) .... but
that they were trying to tie the fine grain capabilities to
accounting/charging operation.

the cp/67 (and then vm/370) virtual machine operation that were used
as basis for security isolation at a number of these service bureaus
had only relatively gross resource consumption accounting. One of the
stated goals that I was given for gnosis was that 3rd party clients
could deploy a broad spectrum of applications and services on the
time-sharing service bureau platform .... and that gnosis would be
able to perform useage accounting by their customers on an application
and service basis (remitting charges to the 3rd party clients) ...
aka fine grain capabilities weren't so much a security construct
(which it also provided) but an useage accounting construct.
