I wonder if there is a step missing to link these together -- that the
links are generally fixed and immobile, or that the scope of distribution
is limited to a set of trusted peers, perhaps?
The point I'm making is that since the interface ID is only unique for the
network device, it doesn't provide any clue as to the identity of the device
owner or traffic transiting the device. Hence, there are no privacy
considerations associated with extension. It is also true that routing peers
are trusted but that is a moot point for this extension In the context of
privacy.
Thanks,
Acee
Sorry I can't be more helpful...
