Paul,

I like option #29: IP extra large. If IP option header #29 is present
starting at the sixth word in the IPv4 header then the "source" part
of the IP header actually contains the four high-order bytes of the
64-bit IP destination address while the seventh and eighth words
contain the 64-bit source address.

I guess it would have been too easy to let us grow incrementally with
only changes on the software side of the house.

Yeah, I can live with that. But I will gripe about it now and then.

Regards,
