I don't think we need to encourage people to do nasty things to computers to
secure them. There are plenty of people capable of doing such things with or
without publicly posted exploit code. The human race isn't as wonderful as
some would like to pretend it is. Can you name one invention that hasn't
been abused one way or another?

Note that I am not saying we shouldn't distribute this code, but I would say
be wary of any litigation or arrest that may come your way if you do so.

At the risk of another dodgy car analogy, would it be OK to drive down the
pavement/sidewalk and run over anyone who doesn't get out of the way quick
enough? That's a form of Natural Selection, is it not? Which is why people
don't really believe in evolution. 

I also doubt any population control activists would through themselves at
the car either, but that's getting way way off-topic.
