Four contest rounds with 2BTC bounty each failed to produce good short-term (2-4 weeks) algorithm, which can beat B&H. Maybe there's no such an algorithm, or maybe the bounty was not high enough for people to publish theirs.

If you really want such an algorithm maybe you should try help pulsecat organize higher bounty than 2BTC. I think there will be much more and much better algorithms published in that case, if for no other reason then it would enable much more time devoted to developing them. It's not exactly easy to do everything right, and it takes time.
