So... there has to be a business opportunity here, for anti-Google Goggle devices.
I'm thinking mainly in terms of wearable QR codes that lead to malware or sites that chew up bandwidth / processing power one way or another, or are just intensely annoying; badgers, for example. But there must be other possibilities; strobes that work just outside the visible spectrum but are seen by cameras, for example. Obviously we don't want to be too antisocial, but I have a feeling that there will be a lot of things like this in days to come.
Bujold-related SF thought - did this happen to Simon Illyan a lot? It's canon for Manfred Maxx in the Accelerando universe, of course.
