Re: Is that a portable access point in your pocket, are you ...
There's a "simple" solution to 4G Glass. Replace your drywall with metal lath plaster walls. Windows with triple pane, ultra low-e treatment on the inside and outside layer. Unless those windows overlook a tower, no cellular will penetrate that building :)
That would block any and all mobile calls and data, including, I presume, emergency calls. Fair enough. The thing that gets me the most though is the picking on Glass specifically, when any mobile device can do what Glass does. And, as various people have mentioned, it's not like cameras don't have SD cards.
So yeah, "preventing people from recording artworks" is a bloody piss-poor excuse for "nerr herr I block you, Glass user." Even then, he doesn't block jack shit asides a MAC address that, given the supposed hackability of Glass, might well be a simple ifconfig eth0 hw ether 00:01:02:03:04:05:06 away from being something entirely different.
I think he wasn't loved enough as a child, myself.
