WinterSnowfall: So, anyone care to enlighten us?
zeogold: Basically, instead of having to download his games via carrier pigeon, he now does so via Pony Express.
I'm not sure that's actually an improvement.
RFC 1149 for "A Standard for the Transmission of IP Datagrams on Avian Carriers" is a more recent standard, sometimes known simply as IP over Avian Carriers, or IPoAC.
It has an updated recommendation
RFC 2549 for quality of service.
And recently in 2011 has acquired compatibility with IPv6 with
RFC 6214.
Clearly it's being kept up to date. I'm unaware of the Pony Express being given the same care. It might have become obsoleted by IPoAC.
