I'll put that in the possible but very unlikely attack vector category
Such a fabricated setup and they only manage 60ft? Because they couldn't find a longer hallway and were afraid of the big outside, or what?
I love it when someone finds a truly clever hack to get side channel information out of a system. Practical or not, this kind of thing keeps the NSA up at night. All it takes is one person managing to use it in the field and then a huge police freakout ensues.
