IMHO both drafts complement themselves pretty well because Erik & Tony's
draft essentially analyze the threats from a IP layer perspective and
Masataka's draft analize the threats from a transport layer perspective.
The problem for Erik and Tony, then, is that IP layer of multi6 is no different from the current one.
I am not really following what you are arguing for. Do you mean to say that
I mean there is no threats introduced at the IP layer of multi6 because the IP layer of multi6 is no different from the current one.
