I think that it should be included in the TODO list. Anyway in-packet
labels should be encrypted somehow, so maybe we should simply hack ipsec
daemons and don't think about trusted network paths?

I have only some experience in MAC implementation. ;-) I'll read audit
chapter of the draft, but i don't think that i can take this task. Maybe
we can exchange opinions - i have nonposix implementation with audit flags
on files and kernel messages on file access, logged via syslog.
As i remember, your posix audit implementation logged quite everything.
There was too much information, and logs grew rapidly.

Well, i tried to understand the difference and the necessity of two these
structures, but failed, i suppose. So i concentrated on MAC, it seems to
be much more simpier to me. ;-)

Would be nice to look at it.
