I bet for $ 1.5 billion neutrino communication (anywhere on Earth) to
its antipode in about 40 msec one way) could be
developed (i.e., the bit rate improved), and I could see some real
market advantages to anyone who had access to it, even
at 100 kbps type bit rates.

Given that, I wouldn't be too surprised to see some physicists and
networking people quietly being hired away by an
obscure new venture...
