Re: 60 ms cross-continent

Many of the traders have set up their short wave radio transmitters for use across the Atlantic. Bandwidth is only 4 
kliobits, but that is enough to send a message saying "buy the SPY Option contracts". It is quite a bit faster than 
fiber.

Yep, why to go around the planet chasing a perfect geodesic with as few relay towers or drones if you can go through 
(shortest distance is always a straight line as opposed to an arc).
While maintaining the speed of light in vacuum since neutrinos don't seem interact with regular matter, that's why they 
are so darn hard to detect.
All you need is an extremely powerful neutrino detector to get you above the 51:49 success ratio. (49% packet loss is 
not what we're accustomed to, but for these guys it's low enough to start making money).
It's quite a fascinating networking world these guys live in, working for a HFT company would be my dream job, always 
pushing the envelope, racing to the bottom, it's like F1 of the networking world just without the safety and fairness 
BS to slow you down.
