Hi,

Thanks for updating this draft. I have one suggestion and then some comments.

The suggestion is to add a section at the end, just before the Security
section, summarising the unsolved issues for shim6 deployment that can be
found in the text. For example it seems that use of HBA or CGA is
incompatible with using DHCPv6 for address assignment, which is probably
quite a problem. (I also wonder whether the Security section should
mention this.)

The comment is that, clearly, exit selection is an unsolved problem.
You do point out that REAP will eliminate address pairs for which
correct exit selection fails, but how about the various techniques
described in draft-ietf-v6ops-ipv6-multihoming-without-ipv6nat?
Also, I suspect that shim6 interactions with MIF and HOMENET need
to be investigated - maybe not in this draft, but they could be
mentioned as open issues.

In any case I support this draft going forward to the AD quite soon.

Regards
   Brian Carpenter
