By the way, you could use a truly random nondeterministic
number generator from Intel,
called Intel RNG and implemented in all of its modern
chipsets: i810, 1815, 820, 840, and so on...
More information is available at
and in Intel 82802 Firmware Hub: Random Number Generator

But I don't know if it's possible to access it from Rebol ;-)
