This might work once, for somebody. Then law enforcement would understand what it is for, what it does, and cut the lanyard/string instead of removing the usb stick before apprehending the device.
Less conspicuous, and no strings to cut.
I.e. instead of comp -> wireless -> device, you go comp -> extender <comp> -> extender <device> -> device -> extender <device> -> extender <comp> -> comp.
