Yeah, I sincerely wish hashcash had succeeded, it seems like a viable route for nigh-eliminating spam. Bitcoin's achievement isn't a radically new core algorithm of any kind, it's using existing stuff in a clever way, to make it self-reinforcing even when thrown at humans. (I mean, yea, that's an algorithm, but you get my meaning)
