Local IPC objects are easy to protect. There are some issues, for ex., how
should sys V messages be labeled: like message or queue. But i think that
it is solvable problems.
Another one is passing labels over network connections inside packets. I
looked through FIPS 188, so i think, that CIPSO will be easily implemented
and work between TrustedBSD boxes just fine. But i don't know how to
achieve interoperability with other trusted systems. I have TSIG docs from
their www.tsix.org site, but there is not much. :(

Did you look through my old patch, where i suggest to import part of
bitstring fuctionality into kernel? What do you think about it?

As i remember, i started your FreeBSD hardening project with POSIX 1e
audit implementation. ;-)))

PS. And what about your polygraph activities? Would we have an ability to
change MAC policies with labels on the fly?
