Several years ago, perhaps as many as 10, there was a simular product under
development that 'saw' the intense infrared emission lines of common Xenon
strobe lights. The developer wanted to place 'flys-eye' lenses on the
wingtips to watch a 360 degree sphere. According to published test results,
it could detect strobes at more than five miles in bright daylight. I
wonder what happened to that idea.

Here is a device that assist with collision avoidance and does not require
any cooperation from the other aircraft:

After reading the FAQs, it does not appear it will be readily applicable
to gliders since in it's current form, it only is effective in level
cruise flight, but it might be an interesting technology to watch.
