Well, you won't have to worry about people dragging anchor across the cable.

You guys joke but here is n little article from last week on the current
state of Neutrino communications:

What about those -- I assume successful -- experiments to fire
neutrinos straight through the earth as a communications medium?
Not sure what the bandwidth of a neutrino stream is.

More fun too when we get global warming under control and there's no
