After having read the entirety of the PC security paper Joanna wrote a while back, I was shocked to see how poor PC security really is. I found it one of the most profound papers I've ever read. As far as I'm concerned, it should be required reading for anyone capable of understanding even the basics. What you wrote reminds me of that feeling and how wide open and vulnerable things really are for those that know what they're doing. It's amazing to me things have been "allowed" to get this bad. All genuine efforts into making things better are very much appreciated and needed by all of us.
