"World's smallest microphone barely visible...” Lecture capture cannot be prevented! Can it be guided, used well?

Even in 1932 - that's a spy belt camera!

"With a little imagination, there is no end to the opportunities for invisible microphones, including 'smart' buildings, defense systems, and a bevy of spy gadgets like pens and watches."

When you are teaching or giving a presentation or almost anywhere doing almost anything, keep in mind that old TV refrain "Smile, you're on candid camera" because you might be.  So the question is not really about policy permitting/encouraging/requiring "lecture capture" of classroom activities.  The question is "In what ways can we take advantage of the new ease with which anything can be recorded and published?"
