> How about SDMI, PICS, or CALEA?
I can't say that I share your concern about PICS. From my point of view
it's an open rating system - it allows a bit of content to be labeled by
any and all rating authorities, from the Catholic Church to Rex's Really
Rauchy Ratings. And I can pick which rating I authority want to use.
It seems that you are concerned with the machine parsible nature of the
rating so that it can be picked up by intermediate devices and
pre-filtered using a rating authority that you would not yourself use.
OK, the answer to that is the same as for much of internet traffic -
end-to-end encryption. Then the intermediate devices aren't going to be
able to read the PICS labels, but you will.
