Instant Messaging With Neutrinos

An anonymous reader writes "A group of scientists has for the first time sent a message using a beam of neutrinos – nearly massless particles that travel at almost the speed of light. The message was sent through 240 meters of stone and said simply, 'Neutrino.' From the article: 'Many have theorized about the possible uses of neutrinos in communication because of one particularly valuable property: they can penetrate almost anything they encounter. If this technology could be applied to submarines, for instance, then they could conceivably communicate over long distances through water, which is difficult, if not impossible, with present technology. And if we wanted to communicate with something in outer space that was on the far side of a moon or a planet, our message could travel straight through without impediment.'"

Submarines?

I, for one, think that anything with the potential for better internet access X feet below the water is an excellent idea.

SETI with Neutrinos?

[norcom]

Should SETI switch to monitoring neutrino transmissions now?

High frequency trading

The first person who figures out how to do this reliably will make a huge profit. There are already undersea cables which exist for the sole purpose of reducing latency between NY and UK stock exchanges. Neutrinos going _through_ the earth (arriving at the Nikkei for instance) would have a significantly shorter time of flight and would give traders a massive advantage.

Will Neutrinos collide with other Neutrinos?

I am not that good in Physics, so I'll post my questions here:

I heard that photons don't collide with other photons, that's why two beams can cross path and still behave as though they were travelling without any hindrance

Will Neutrinos behave like photons? Or will Neutrinos collide with other Neutrinos?
