OK all you experts, assuming the advances can be made to increase the range to hundreds of miles, what about interference? If you have a military theater of operations with 200,000 RFIDs all transmitting at the same frequency at a range of hundreds of miles, how will you not have interference? This isn't cars zooming single file under a reader, or jeans coming out of a store one at a time.

Could you have a reader that sends out a narrow beam and scans regions of an area, much like the ray of a cathode tube scanning the individual lines of the display screen? A big eye in the sky, slowly scanning the ground back and forth for individual RFIDs?
