Military has been using this kind of network on ships at sea for decades.

  That's interesting...aligning a laser spot beam between two ships moving, pitching, and rolling seems non trivial.

    Actually, considering the distances I would assume that high-entropy high-frequency noise near the laser such as people walking nearby, engines roaring, air currents, etc are much harder to deal with than the low-frequency predictable movement of the ship caused by large waves.

      >low-frequency predictable movement of the ship caused by large waves. Well, I was thinking that combined with whatever navigation is going on as well. As a layperson, waves don't seem predictable to me.

        On micro- to millisecond intervals, plus the dampening effect of a 10K to 100K ton ship, waves are pretty managable.
