One of the main factors in crypto seems to be a source of random numbers which most computers don't really have. Wouldn't it be ppossible to apply the Mafia-numbers-game solution? i.e. For your numbers (or seed for a large volume of numbers) take a random pubically accessible number like the last 3 digits of the attendance of a sporting event. I have never seen any formalizations, but that type of number should be as close to totally random as possible.
