It took you quite a lot of time to realize AA does not do IPC (and all the implications of that). I do not think Linux _users_ can do informed decision here. Novell marketing did too good job here. Heck, even I am not sure if I understand the implications of not doing IPC confinement. Is shared memory commonly used in a way that allows exploiting? I know it is a problem, and you probably could kill init from hacked apache..... but what would you do to break out of jail?
