So Google bought Skybox. Now they can correlate all they collect about your purchasing/browsing/emailing behavior along with actual tracking imagery. Of course they will need lots more satellites to randomly track anyone but that is only if they need full coverage, realtime data.
At this level of magnification, cars are resolved but not people. However, with cell phone tracking added in you could probably keep tabs on position alone. Bigger telescopes would let you resolve people so it may just be a matter of time. As Google said, "if you've done nothing wrong, you have nothing to worry about".
