Nature should do their homework (Score 1)

There's actually published work on this (to Nature's credit, this is fairly recent work). This system called Vigilante [1] (incidentally from Microsoft Research) does it all: automatice detection of worm, automatic distribution of signatures, automatic generation of "filters" and protection mechanisms. In the paper, the author's don't use honeypots, but there's nothing in the system that precludes their use.
