French researchers have developed wallpaper that’s designed to trap Wi-Fi signals, without interfering with radio or cellphone signals. It uses conductive ink containing silver crystals to to block a Wi-Fi router’s operating frequencies: your router should work as expected, but the signal won’t travel beyond the wallpaper’s boundaries. While currently only a prototype, researchers at the Grenoble Institute of Technology hope to make the wallpaper commercially available early next year.

But perhaps the Romneybot 2012 could work some of its Vietnam-era missionary contacts and procure an early-adopter supply to help avoid embarrassing episodes of signal glitches like this one:
