You may all now start the proselytizing about how IP NG
should have separated the endpoint identifier from the
endpoint locator and fixed most of this as a side effect.
Or how any such thing would have been evil. Or how trying
to wedge this onto IPv6 at this point is (the future|doomed
to fail).

*Runs. Hides.* (Been reading too much of the IPv6 griping
on NANOG.)
