Right - yes understood. I guess the actually title of his talk is less interesting to most (but its good for people to realise ACLs and such are just not practical anymore - its a worthy talk subject !). I think I discovered that about ACLs a while ago, but assumed it was a specific problem with whatever I worked on, not that its a general issue with the ACL approach.
