This is very cool to see. When I discovered and subsequently purchased my framework back in October I had an idea for a homebrewed, 3D printed expansion card, where plugging it in/activating it immediately executes dban (or some other, better alternative).

Or you could always just carry an enormously strong electromagnet on you :-)

Very keen on picking one of these up purely for the novelty, price isn't too bad. Although I think the demographic who would and could actually benefit from a failsafe for having their laptop physically yanked away from them is quite small.
