One of the migration paths suggested for IPV4 to IPV6 migration is to tunnel IPV4 packets within IPV6 packets. IPV4 packets do not provide for an adult/minor tag, so until the transition to IPV6 is fairly well along, this approach will be ineffective.
Neither, for that matter, do IPv6 packets -- there is no provision for them. Furthermore, were anyone to create an end to end header of that sort, it would be eight bytes of wasted space in every packet in the net, especially since the implementation of such a tag is a technical impossibility as there is no way to force the originating system to tell the truth. The internet and the culture are coming into conflict in a big way, and I don't believe that both of them can survive. Perry
