You have probably read the April Fool's Day RFC 1149 (A Standard for the Transmission of IP Datagrams on Avian Carriers) (available at http://www.rfc-editor.org/rfc/rfc1149.txt).
You may have read http://www.blug.linux.no/rfc1149/ which is about an implementation of it. Maybe they should try it in South Africa. They appear to have the hardware.
A South African information technology company on Wednesday proved it was faster for them to transmit data with a carrier pigeon than to send it using Telkom, the country's leading [I]nternet service provider. Internet speed and connectivity in South Africa are poor because of a bandwidth shortage. The 11-month-old pigeon, Winston, took one hour and eight minutes to fly the 80 km from Unlimited IT's offices near Pietermaritzburg to the coastal city of Durban with a data card strapped to his leg. In that time, just two per cent of the data was sent over the Internet."

The joke used to be about the bandwidth of a station wagon full of magtapes, and now, the hardware has been miniaturised to pigeon-size. I am amazed at he advances in computer technology.
