Tunnels are a non-starter because people are not going to move from a 160-bit header to a 320-bit basic header, followed by numerous other bloated headers and then add more headers just to tunnel across the legacy IPv4 32-bit Internet. The laws of physics can not be changed. You can only push bits so fast thru a particular medium. With the liberated American marketplace, free from the I* society regime, the focus is on SERVICES. Services are now being developed and deployed that assume minimal bandwidth requirements and efficient routing. IPv16 only allows native mode, there is no tunnel mode. Not only that, the data rides inside of the IPv6 basic header in the unused bloated address bits. The 320-bit header is the packet, the only packet, for many services.
