Also useful as camouflage? There is something running around now that renders the camouflaged person/item invisible for all intents and purposes.

I don't know, possibly. Seems a natural for stealth technology, too, doesn't it? Interesting that they didn't mention anything about stealth?

I'm a believer in openness in academic research for most things. But it amazes me sometimes just what the gov't will and will not allow to be published; i.e., I would think this find should be classified.

Was my first thought. If someone was wearing a suit made of materials that reflected no light in wouldn't they effectively be invisible?

That either uses cameras, or (much less advanced currently--it has worked on microwaves, but the visible spectrum requires nanotech structures currently too small to make) nanotech properties which have light flowing around the object, similar to water in a river flowing around a stone in the river.
