If you're really paranoid about someone intercepting your home WiFi network, maybe someday you can set up a wireless network that transmits via visible wavelengths (so a wall would effectively block out would-be eavesdroppers)
But windows wouldn't. Also, it'd be fucking visible, so unless you were in the mood for a Pink Floyd Planetarium Experience, godsdamn annoying.
