My point was that, except for the mechanism for PD, I don't see a
substantial difference here that would e.g. prevent this from being
developed for IPv4 (in addition to IPv6). -- Yes, I know we need to
deploy IPv6... but I don't think you can expect people to get rid of
their *working* IPv4 devices... (i.e., not sure why any of this
functionality should be v6-only)

I think this deserves a problem statement that clearly describes what we
expect to be able to do (but currently can't), etc. And, if this is
meant to be v6-only, state why v4 is excluded -- unless we're happy to
have people connect their IPv4-devices, and see that they cannot
communicate anymore.
