That's a neat idea, and something I'd never thought of before.

I'd imagine the customers here would be looking for a way to keep an eye on competitors? Ford would like daily overhead shots of GM's factories and parking lots, McDonalds would like to check on the length of average drive-through queue at competitors, etc? All in near-real time, without waiting for quarterly earnings.

On the other hand, weather might render this too unreliable for the needs of such customers - "how busy have the Bay Area Starbucks been since they've released their Pumpkin Spice Latte?" "Uhh, not sure boss, it's the 30th cloudy day in a row, we can't see anything".
