The only acceptable way of classifying material, as I see it, is making the system totally opt-in. (someone mentioned this earlier)
Instead of forcing the .bad/.porn/.xxx on unwanted content sites, you could get .kids/.safe and make siteowners apply for that. Then you could filter out all content BUT .kids on your children's logins.
It would be like security certificates, demanding proof from an indepent party that content is good. Like Thawte etc does today with SSL certs
