I think I can give it a pretty nice use: distributed ring signature over long distances. We can distribute people over different regions for redundancy and form long distance encryption channel to deliver a signature of some data, and use it to make consensus with enough provenance. Kind of like e-voting but with stronger assumptions.

By using a long distance communication device this eliminates the proximity strike problem. This could easily be extended to say like distributing the voting rights to different generals at different regions, and given that the device is genuine and not modified, can be a hardware voting key to say like launch the nuke in secrecy or not.

Whether adversarials can use the radio signals that it emits to triangulate you and thus track you is another story, though.
