Actually, the default is 2+n, where n is chosen from a geometric
distribution around the config option CoinWeight (which really needs a
new name). CoinWeight is generally .01 these days. Is there any known
value to choosing path length this way against the adversary we expect,
or should we simplify?

Actually, I should make route selection code that can do it any of those
ways and still be shiny. We will see. :)
But you're right, we should solve this. At the least it should go as an
open research problem in the design paper. If you have more of an answer
than "gosh, hard problem" then let's hear it. :)
