It's indeed the MHAP way of solving the problem and I don't think people
want to actually adopt it at all for various political (read: cashcow)
reasons :( And I certainly am not even going to bother pushing for it as
for me it doesn't hold any value, I am pretty happy with a little chunk
of PA space as an enduser. The companies that need such a solution
should be pushing and going for it.

It's only the solution I see fit to solve the problem were everybody is
making problem over and I really don't see any chance of it getting
accepted simply because of the political reasons, just like most likely
shim6 will not make at as some folks really don't want to give that kind
of independence to people, just like they are opposed to "PI" in the
first place... it is also why I say it might take multiple years, it
might also take forever.

Greets,
