idea: github wars

here's the idea:

• programmers go to a github wars site and click I want to compete
• they are given an issue from github (maybe people could tag suitable issues)
• they are given a 1 hour time limit (they must commit within 1 hour of being told which issue to work on)
• another programmer is also given this issue, and 1 hour (not necessarily at the same time, so the first programmer's code would need to be hidden from them)
• after both programmers have committed, a winner is chosen by the person with the issue (and perhaps by some other programmers)
• programmers get a chess-elo-style score based on wins and loses
