I am on the FOCS program committee. The deadline for submission is in four days, and I look forward to reading in detail about the exciting progress that theory is seeing!  (To pick a random exciting paper: this.)  This time around I will also run a small private experiment and report on it after the decisions.  I was looking briefly for an online system that would allow me to commit to the experiment with the usual cryptographic guarantees, but couldn’t find it.  I thought maybe I could commit now to using a definite future value, say tomorrow’s closing value of the S&P500, as a seed for a commitment scheme.  It would be overkill in this case, because the experiment I have in mind is not so important, perhaps, but in other scenarios it may be useful to be able to do this without much effort.
