Don't laugh too quickly. Given a slow enough connection and a big enough file, the pigeon (with flash drive strapped to leg) will win.

Except that RFC 1149 specifies a single IP datagram per pigeon, which means it will be slower than even the slowest of dial-up connections.

IPv6 jumbograms to the rescue, 4GB per packet

That was published on 1st of April. It's an april fool's joke. There are loads of April Fool's RFCs. It's not a litmus test for reading, it's a community having fun.

BTW: A group tried the IP over Avian Carrier: http://www.blug.linux.no/rfc1149/ The ping times were unimpressive.

I think the litmus test being suggested is to include the joke RFC in the reference section of a different technical specification as a way to verify the specification is being reviewed in detail.
