Ok, this was pretty cool. Granted its expensive to set up but imagine two stations on opposite sides of the planet sending a constant stream of neutrinos to the other. On that 'carrier' you modulate data.

Now compare that to running a transworld cable half way around the world. Not only do you get a latency improvement of 33% (going 8K miles instead of 12K) you don't have to worry about ship anchors or anything else screwing up your link.
