An historical note: In the early 1970's I did some contract programming work at the Air Force Cambridge Research Lab at Hanscom Field in Bedford, Mass. Their main computer was a CDC 6600, a super computer in its day (60-bit words, 10 MHz clock). http://ed-thelen.org/comp-hist/cdc6600.html
The wall separating the computer room from the hallway had a large picture window facing the console, with its two (vector-scanned) CRTs. http://www.research.microsoft.com/users/gbell/craytalk/sld031.htm. There were curtains on the window that were to be drawn whenever classified programs were run. In addition, I was told, there was a large board that the operators were supposed to place over the console. I don't know if these precautions were based on analyses similar to Kuhn's excellent paper or general paranoia, but there is a lot to be said for the later.
