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?
