Using carrier pigeons to transmit electronic data isn’t a new idea. There’s been an RFC standard for it since 1990:
This memo describes an experimental method for the encapsulation of IP datagrams in avian carriers. This specification is primarily useful in Metropolitan Area Networks. This is an experimental, not recommended standard.
A few months ago, a South African ISP raced a carrier pigeon against its competitor’s DSL; the carrier pigeon won.
And last week, the ABC’s Hungry Beast TV show staged a similar race, sending 700MB of classic Marx Brothers comedy 150km from the country to the outskirts of Sydney. The competitors: Telstra’s crappy ADSL; a Ford Falcon (no Holden? Sacrilege!); and a carrier pigeon. If you’ve ever used Telstra’s ADSL, you can probably guess how the race finishes.
