I should point out that in a sense he is right: There is no _pure software_ method of generating random numbers. Adding hardware changes that.
A major computer company (SGI?) had on their website a few years back a truly random number generator that was, mainly, a camera looking at a lava lamp.
Intel sells
hardware that will generate true random numbers by measuring "thermal noise from a resistor."
I'm sure there are many other examples. There is no good excuse for not using such a system if you need secure random numbers. Of course, that didn't stop Party Poker from using using pure software for generating their "random" numbers... unthinkable...
Interesting, anyway!
