Sure. I was thinking of an IC design, in which

Because with a pRNG we can sometimes prove very important
things, while with a RNG we can prove very little (we can't
even prove that entropy actually exists, let alone that we
can collect it).

Don't be silly. Of course we know that

Wrong question, the -right- questions is...
What is -random-?
It means unpredictable, this means unrepeatable. If it repeats then it
-must- be predictable; that

Both applications are orthogonal. PRNG != entropy.

Oh surely you can do better than that - making it
hard to guess the seed
is also clearly a desirable property (and one that
the square root rng
does not have).
U can choose any arbitrary seed(greater than 100 bits

For the start, before deeper analysis, it would be a good idea to run Diehard
