I finally got around to reading "Defending Aginst an Internet-based Attack on the Physical World" [8p. PDF]. Very interesting attack, the real world example from the latest CryptoGram is very good. It's of course nearly impossible to defend against.

The OpenBSD/DARPA saga continues, from "Re: Darpa now denies it..." email: "... Words hurt them dearly, and they react. They break promises." The broken promise part of it is also what I'm most annoyed by.
