Re: [RAM] Different approaches for different protocols

So let me propose something:

1) For IPv4, use LISP encapsulation as spec'ed in the -05 draft.
2) For IPv6, use header address translation (of the high-order 8-bytes),
   spec that out as GSE++.
3) Have both use the same mapping database infrastructure.

Comments?

If we added 2) to the LISP draft would people be happy with that?
