=>We have discussed to define new capability attribute in the mail-list
before. I guess this approach could avoid leaking mapping information into
interent routing system.

=> Mapping information distribution could be done in the side of initiator's
network.For example, in IPv6-IPv4 translation scenario, mapping information
could be distributed based on IPv6 BGP message.

Thanks for the discussion.
