As an aside: was robustness (routing around damage) ever an aim of the DARPA project? I hear conflicting things, and it seems to be part of the folklore now.
That's a really good question. The phrase is sometimes called [John] Gilmore's Law. http://www.chemie.fu-berlin.de/outerspace/internet-article.h... It has certainly been said many times that DARPA was "researching a decentralized system that would be robust enough to survive and function even if most of the network were destroyed".
But that was in the event of a nuclear attack - presumably a bit more random than governments with Big Switches. Of course, NO networks, NO re-routing.
