Is this an area where IP over WAVE would differ from any other form of
IP? I worry that if we start listing things that MAY happen, we start
to imply that things we leave out of the list aren't allowed even if
they were just forgotten.

It might be better to say "Any security mechanism at the IP layer or
above that may be carried out for the general case of IPv6 may also be
carried out for IPWAVE".

Cheers,

William
