Say they manage to sustain these channels over distance, and figure out the pulse timing to be usable for a relatively sustained link... What happens on a snowy day? (or other weather types with lots of interference... hazy/dusty days, etc). What effect would a stiff wind have on this? What effect would it have on a person walking through the plasma creation beam?
