of dwell time and bins of flight time. Certainly easier to reason about
how effective it is than some crazy probability distribution, at least.
Ideally, we'd make the bin width such that they end up with uniform
person-density in them, which means we'd need stats on the avg dwell and
avg pairwise flight time.
Actually, it may be that all bin-widths is well below what is a noticeable
amount of delay, so maybe we need only one bin.
Except, this makes me realize we're still going to break HTML5 games that
use keyboard input. Or at least make people wonder why they suck so bad at
them when using this privacy mode..
