Using this message as a good excuse to bump this thread ;-), I thought I'd let you know that I got a chuckle out of your link explaining the "J. Random" thing!!! :-)
I also own a T-shirt that I bought from the author of PGP, when he was going through his little difficulty with the State Department.
I wear it whenever I get my picture taken by the State for my driver's licence. It's a federal felony to wear it. Or it was.... We won that one.
