Casey,

Thank you introducing TOMOYO Linux. I really like your idea of
simplified MAC (and you work so hard!). I also find advantages
of AppArmor for distributing policies with less hustle. Finally
and most importantly, I respect SELinux as the first in-tree,
flexible and reliable security frame work and respect developers
involved.

As a project manager of TOMOYO Linux, I would like to
push it, of course. But I noticed, if each of LSM module
developer begin pushing their own code, that's not for the
sake of Linux and we may end up with chaos.

Instead of pushing TOMOYO Linux, I started developing
comparison chart of security-enhance Linux implementations.
The current version can be found in

http://tomoyo.sourceforge.jp/wiki-e/?WhatIs#comparison

I would like to receive feedbacks from Stephen, Crispin
(you already have a comparison, though :),
Casey and any people interested in. If possible,
I would like to include opinions from BSD people.

I would like LSM to be the result of common requirements.
"Common" means good in general, but not always for security
perspective. IMHO, I think it is possible for us to get to the
conclusion not to have a framework.

Cheers (and with love to Linux),
Toshiharu Harada
