I Want Some Of These

I mean, I honestly can't see what tactical advantage they'd have over laser comms considering the state of our potential adversaries in the surface world, but this is just about the coolest thing ever:

"The U.S. Navy is field-testing a new short-range communications device called LightSpeed that could soon let sailors talk securely up to two miles away -- just by looking at each other.
"The device uses infrared, similar to that of a television remote control, to transmit audio and visual information. To overcome range limits, LightSpeed connects to ordinary binoculars and uses the optical lenses to amplify the signals. Then soldiers on either end can simply plug headphones and a microphone into their binoculars to talk to one another.
"Out of the right eye there is an invisible beam that goes out and the LED is the same LEDs that you have in your remote control," said Leo Volfson, president of Torrey Pines Logic, the company that makes LightSpeed. "If the user on the other side has a similar device he will be able to talk to you or pass data."
"Master Chief Jim Blessé, of the Office of Naval Research, which is funding the project, said LightSpeed offers a more secure channel than radio or lasers."

Sweet... Not much use for modern naval comms, but still sweet...
