I'll nit and say we only have 5K nodes, including 1K exits and 2K
guards but it's possible. I proposed (and intended to do before I got
sidetracked) that we just go through the exit probability percents and
tick off which nodes we believe are run by trustworthy people, and
just see what percentage we get to. I think it will be less than 50%,
but greater than 25%.
