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
