"Apple already does a good job of this in Leopard — its got a nice system whereby if you go to a web site that's not there [on the white list], the parents will log-in, authenticate and add that site on demand. And just incrementally keep adding until they stop asking. That stuff works — and again you notice that's a client-side decision, that's not a network side decision."
