What form RC4 distribution have?
BTW, if we ever think about replacing our current variant with such complex and unknown (at least to me) thing as RC4-based PseudoRNG, I simpatize more to Knuth variant mentioned by David Schultz: http://www-cs-faculty.stanford.edu/~knuth/programs/rng.c RC4 is good for hashing existen randomness, but is it good as PseudoRNG? -- Andrey A.
