Wi-Fi Shielding Paint
I have no idea how well this works, but it’s a clever idea. From Information Week:
Force Field Wireless makes three products that it says can dramatically reduce the leakage of wireless signals from a room or building.
One odd side-point from the article:
Force Field has been trying to interest the Department of Homeland Security, but discussions are ongoing, Wray says. “Ironically, we have had foreign governments contact us—from the Middle East. Kind of scary.” Wray says he won’t sell to them.
I wonder what’s so scary about selling metal paint to a Middle East government. Maybe the company thinks they will use the paint to “cover up” their misdeeds or poison political prisoners?
