I am part of the team which runs the OpenStreetMap.org infrastructure, we also get a lot of weird and wonderful requests / emails. .mil, .gov, .edu and GeoTLD variants.
I should really do a write-up sometime.
You should compare notes with the trove of weird emails that Daniel at haxx.se gets (the curl guy) because his email address is in the curl license text appended in the fine print of a bunch of products.
I encourage you to make it! That sounds like it could be a really fun read.
I really want to read this!
I remember being in Tel Aviv for work, and pulling up maps to plot out a bike route from the hotel to the office. Only to find that the entire route is blurred out online. Turns out our office was a few 100 meters from something important to the IDF, so no map/route data available. Too far to reasonably walk, and didn't want to try a bike without knowing there was a reasonable route...
