RE: I-D Action:draft-donley-ipv6-cpe-rtr-use-cases-and-reqs-00.txt

Thanks for the feedback.

We're aware of the draft-ietf-v6ops-ipv6-cpe-router.  We address many of
the same use cases as the cpe-router document.  The main difference is
in approach - we tried to include additional architecture/operations
information for how such a CPE router would be deployed.

Thanks for the pointer to RFC4864.

Regarding Section 7.3, we agree that more needs to be said.  We included
it in "Future Considerations" to be updated in a future version.

I'm very curious why this draft doesn't refer to
draft-ietf-v6ops-ipv6-cpe-router. We certainly don't
want two competing documents, so can the authors say how
they plan to approach this?

I'm also curious why RFC4864 isn't mentioned. That's not
normative, but I would expect any draft in this area to
at least mention the scenarios mentioned there.

This seems like far too short a discussion and far too short a list.
The range of coexistence (not transition) solutions is much larger
and it's far from clear which ones will be widespread.
