It think this approach is worth pursuing, so that we can also see what's 
there, and determine if there is a need for some form of stacking, or 
whether we can consolidate some of this into library code which the 
various LSMs utilize.

People who don't want to run SELinux / AppArmor / Smack / TOMOYO etc., run 
can still get some protection.
