    Our local University, FIU has a team that works on CERN projects in Miami. My daughter accesses observatories on the other side of the world queing up telescope positioning and camera shots in multiple light spectrums from her work station at FIU. It's fascinating how it works. More interesting is how the computers are configured to make it happen.

      The NSA's requirements are a bit different; easier in some ways (many more intake points, fewer access points), harder in others (hiding the data flows).

      At this point, though, it's just engineering. Thirty years ago, it wouldn't have been practicable: a washing-machine sized disk device could hold less than a gigabyte, and had a maximum data rate of less than 10 MB/s. Networking trunks topped out at a few megabytes/second. Most computers clocked at a few megaHertz, and took multiple clocks per instruction.
