Dear Y Combinator, we bet you we can solve a problem of yours in 72 hours.
Ambitious, risky, and likely to be ignored by YC, but I like the spirit :)<p>Would be fun to see them play this game with you though (I'm quite curious to see how you guys work things out if they challenge you to send an iPhone to Mars and back, for one example of many, many problems they could ask you to solve that you couldn't really take care of in 72 hours).
