I think this is a decent theory, but with automation, the delta between
"Date" and/or the signature timestamp and the first replay can be rather
small, certainly smaller than any reasonable first delivery window.  It's
basically the "x=" problem.

I don't want to get into implementation discussions before we even have a
charter, but I'm curious about how this could be made effective.
