Adjustments would be made not to the cable, but via a dial on the control unit.
Shimano already has battery-powered cable-less electronic shifting. I actually kind of like the concept, because it permits one to locate multiple shift controls, e.g. one at every hand position along the drop bars, and it could be morphed into an integrated single-control system, if desired.
