I think the consensus we had in the past BoFs and discussion in and around this
topic can be summed up as stating that homenet deliverables will:
- coexist with (existing) IPv4 protocols, devices, applications, etc.
- operate in a (future) IPv6-only home network in the absence of IPv4
- be IP-agnostic whenever possible
In other words, anything we do for the IPv6 homenet cannot actively break
what's already running on IPv4. Also, trying to define what the IPv4 home
network should be has long reached a point of diminishing returns given the
effort in doing so coupled with our ability to significantly affect what's
already deployed. There's still hope we can help direct IPv6, as such that is
homenet's primary focus. However, when we can define something that is needed
for IPv6 in a way that is also useful for IPv4 without making significant
concessions, we should go ahead and do so.

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)
Chaining NAT boxes already work. I also feel that we shouldn't put in a lot
of work to develop IPv4 further, that focus should be put on IPv6.
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.
IPv4 should be excluded because it's a dead end, and we all know it. We're
just disagreeing when it's going to die and how.
