Consider the implications of this with improving facial recognition techniques. Everyone's face is, or will be, tagged, either by facebook and its ilk or governments, and will be readily recognized when streamed into the cloud from someone's wearable device. Just walking down the street wearing these goggles could potentially reveal the location of anyone you see. I can foresee publicly acceptable disguises and clever obfuscation devices becoming popular. Perhaps burqas will become in vogue ;)
