Announcing 2003::/16 during tests of "shipworm"

Although I welcome your will to participate on IPv6 protocol development,
I cannot agree with announcing 2003::/16. There are active production IPv6
networks over the world already which are connected to 6bone and receiving
this non-official prefixe. It is the same as advertising 197.0.0.0/8 over
the Internet which is, according to IANA, reserved prefix.

Anyway, I don't see the point of using the Shipworm. The cleaner solution
is to configure IPv6 on the box, which provide NAT for the private network.
