Basically, restart an full-disk encrypted device when loss of signal or drop in temperature occurs. Have something similar on your desktop. Wear a BLE Android watch, and make sure your devices restart when they get out of reach, or when put into a Faraday bag, or when dropped in liquid nitrogen :)
Yeah, it's still possible to defeat, especially if someone knows your setup, but it's at least pretty damn close to foolproof. If you sense trouble, just run like hell and lose the signal
grugq removed the PoC repo in prep for a product launch, but here's a fork of a project that's a partial solution: https://github.com/RagnarDanneskjold/darkmatter
