Better Networking Through Nature
The New York Times has an interesting piece about applying lessons from nature - specifically ant colonies - to solving networking and other problems. Not quite on the same level as Spidergoats, but intriguing nonetheless.
Those of us who have played Sim Ant before would probably see some advantages to using "pheremone" based routing on the internet. There is a fundamental difference, however, between real ants, and computers on the internet. Real ants are genetically programmed with loyalty to their hive. Computers, on the other hand, are plagued with script kiddies, worms and greedy lawyers.
The potential for havoc is high if this scheme is ever implemented and script kiddies all over start leaving fake "pheremone" trails around the internet.
