Another solution is if the machine has a soundcard. Cranking up the white hiss of the input amplifier will give you plenty of randomness, especially for this, where non-predictability is more important than statistical-even distribution. Most will do, what, 192K/s at stereo 48K 16bit sampling? -Tom
