Right, but note that the seed is not enough to ensure deterministic output because of jitter in the network. > If the environment variable VIFF_SEED is set to the empty string, VIFF > already uses /dev/urandom by using random.SystemRandom for random > number generation. This possibility is not documented however. It's documented in the final paragraph here: http://viff.dk/doc/util.html#viff.util.rand I will of course agree that it could be made more explicit :-) -- Martin Geisler Mercurial links: http://mercurial.ch/
