Having frets that shift is an interesting
engineering problem.
One could have a hydraulic insert of some sort or possibly a servo
controlled wedge system incorporated in the fingerboard. Tricking out the
actual fret wire might get you enough tolerance not to have
visible/tactilely nasty seams Somebody somewhere had to have tried
conceptualizing it.
Yes, I came across a Viola da Gamba designed to play Persian scales.
Moveable gut frets. Possibly a little simpler than you had in mind.
Ah, thats a strategy I didn't consider. One could have sort of a traverse rod
dealie with cams to lock 'em down.
