>How does this interact with softwires?

Sam,

  This protocol fits into more or less the Mesh problem of softwires
(section 3.1 of draft-ietf-softwire-problem-statement).  The problem
statement says:

>   It should also be noted that the mesh problem can be considered as a
>   derivative of L3VPN, where the core provides transit in one address
>   family and the islands are connected via L3VPN of another address
>   family.

And indeed, the draft-ooms document is more or less an application of the
L3VPN technology to the IPv6 address family.

  I don't know what the softwires participants' position is with respect
to this draft, but it predates the softwires work [at least, by that
name] by about 5 years.

  Bill
