Sure, I mean the low-rez version is pretty cool but no one would ever fund it. Related: The ISS usually has live video streaming from some external cameras. http://www.ustream.tv/channel/live-iss-stream (If it goes all blue, just give it a minute.)

Would love to read more about this.

I'm not sure if tracking and identifying individual humans from orbit is even optically feasible, but it can certainly be done for cars. And tanks.

Such a thing would be used by both sides in urban conflicts to "see round corners" and track targets.

If 40+ years ago NRO had meters resolution imagine what they could have today...

> A perfect 2.4-meter mirror observing in the visual (500 nm) would have a diffraction limited resolution of around 0.05 arcsec, which from an orbital altitude of 250 km would correspond to a ground sample distance of 0.06 m (6 cm, 2.4 inches). Operational resolution should be worse due to effects of the atmospheric turbulence.[24] Astronomer Clifford Stoll estimates that such a telescope could resolve up to "a couple inches. Not quite good enough to recognize a face".[25]

I suppose it depends on what we call high resolution, but I know for a fact I don't want a camera on me 24/7 when I'm outdoors. There are also whole cultures where personal photography is bad, and while it's not practical today to complete fufill their wishes, a livestream of the earth in high resolution would be pretty horrific I'm sure.
