Neutrino communication has been suggested used for high speed trading. The advatage of Neutrinos is that they can travel trough earth. The distance through earth is shorter than along the surface. This means one can save milliseconds in travel time between financial centers.
Advantage: Can go through earth. This gives shorter distance than sending a light signal along the surface of earth. Speed close to c. Any information techncology that can go through earth instead of along surface of earth will likely be the winning technology in the high speed trading race.
Disadvantage: technology not fully developed and likely very expensive to develop.
