Interesting. I don't understand why. Care to explain Moe?

But unless you sample a noise source at exactly the same billisecond
the chances of getting the same result are pretty slim, surely?
I agree (as I stated in my post yesterday). I don't understand why different noise sources would be better than a single noise source. Unless, by your statement, "at the same time" you mean at the same ∗instant∗ and are sampling the noise with the same clock. (in that way sampling different noise sources with the same clock should always give you non-correlated results)
Also, (given that I don't know anything about electronics) doesn't your term "seed" imply a digital (pseudo-random) noise source and not an analog noise source (which I guess is also pseudo-random though in a different way).
Am I wrong?
