I think these are FreeBSDisms?  NetBSD just incorporated a clean-room 
implementation of kauth, which is Apple's kernel authorization module, 
and which shares some common ground with these topics.  I have spoken to 
the author of kauth, Elad Efrat, and and said he is willing to provide 
any information that you may need.

The following URLs provide some information about kauth:

http://mail-index.netbsd.org/tech-security/2006/04/18/0000.html
http://developer.apple.com/technotes/tn2005/tn2127.html

I've bcc:ed Elad on this message, and I hope that he'll get in touch 
with you.

	Cheers,
