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?
