If the assumption is that any IPv6 over NFC is only send in secured networks, 
maybe the higher layers are not further protected, and therefore a gateway 
should probably not just take the IPv6 packet and send it out in the Internet 
as is. I wonder if that is something that should be further discussed or at 
least mentioned in the security consideration section.
