It is probably time to re-read the famous Internet protocol specification "RFC 1149
" with the title, "Standard for the transmission of IP datagrams on avian carriers." I will quote some of the more important parts of this technology straight from the spec.
Avian carriers can provide high delay, low throughput, and low altitude service. The connection topology is limited to a single point-to-point path for each carrier, used with standard carriers, but many carriers can be used without significant interference with each other, outside of early spring. This is because of the 3D ether space available to the carriers, in contrast to the 1D ether used by IEEE802.3. The carriers have an intrinsic collision avoidance system, which increases availability. Unlike some network technologies, such as packet radio, communication is not limited to line-of-sight distance. Connection oriented service is available in some cities, usually based upon a central hub topology.
Transmission by avian carriers didn't take off quite as well as, say, ethernet, but it is still an interesting idea. I do not know what companies on the Nasdaq are investing heavily in avian carrier technology, but it might be worth checking into. It's really ideal for sailboats - robust, long distance communications, cheaper than satellite communications, and if you find you are really hungry at sea makes a nice snack.
