I've seen a fair number of Wi-Fi ad hoc networks come and go since I got into Wi-Fi in 1999, and all of them were far more trouble than they were worth. Byzantium looks better on a number of counts, and I wonder if any readers have tried it.
Also from Slate: Kids who passed the marshmallow test not only did better in nearly all aspects of life, but they weigh less at age 45. Their super-power may be simple impulse control, or it may be more than that: I've long suspected that some people are simply addicted to wanting. If it isn't the marshmallows it'll be something else.
