That said, I saw an OO based OS demonstration by some people from the University of Kentucky on the "Choices" OS. I was impressed when they implemented ACL's in about ten minutes, using inheritance. Of course, they had done it before (Any sufficiently advanced technology is indistiguishable from a rigged demo ;-)).
