there's a difference, or at least should be with a PRNG, between knowing the 
entropy (seed) and knowing the current value.

with a central server you only know the current value, the next value should 
be statistically random.

with a coordinated seed, you know the internal state of the PRNG which renders 
it statistically predictable.

PRNG's only appear random due to information hiding (the seed) which is why 
the Doom approach works in the first place.
