I've worked in facilities where this ban existed, but not for the stated reasons. These same facilities don't even let you bring in a transistor radio because it is so easy to turn it into a transmitter. The EMI part is usually part of the dis-information. These same places also prohibit personal lap-tops, under the TEMPEST excuse. What they are really worried about is espionage. I'll bet they have a ferocious firewall too. > -----Original Message----- > From: Daniel L.
