A (very) short post about Glass

Within 10 years I will be able to buy a pair of glasses that to all intents and purposes appear the same as my current prescription specs but have all the affordances of Google Glass.

I will be able to look at an exam paper and have the answers fed back to me on a screen that is invisible to all about.

Short of constructing a Faraday cage around every school hall, just how is the examination system going to deal with this?
