B. Pull random numbers from a hardware RNG. Could use a site such as random.org (my concern though would be trading the risk of the OP for risk of a new entity). This random # would be used as the server seed (cannot be used as the seed # for hashing since would not be provably fair).
why not pull random numbers for use as (additional random to) server seed from the blockchain (every block or so)?
That actually seems like a pretty good idea. What you think Doog? Would that be difficult to implement?
