Obviously for the bottom octave, moving the head/mouthpiece in and out affects the relative length for the lowest notes which use most of the length of the flute less than higher notes. This means that tuning a flute (and any other woodwind instrument) by moving the mouthpiece in/out of the body is a compromise. If a flute was in physics terms a perfect double open ended oscillator then the second octave (and in physics terms all harmonics) would be affected in the same way. 

True but there exists no such animal (and never will) because of the mathematical functions of the harmonic series. It is impossible to have all the harmonics affected in the same way since there are so many mathematical proportions in scaling that change for every note. You can never get a perfect scale from a fixed scaled oscillator serving numerous harmonic functions. You would need a variable oscillating scale capable of instantaneous revoicing. That means at least, tangibly changing physical bore/length ratios for each note, etc. (think of organ pipes)
Quite frankly that is only possible with theoretical physics. The only comprehensible method at present would be using a fourth dimensional time intersection so that individually fixed frequency specific flutes could be played simultaneously utilizing a fourth dimensional interface (time).
OK never mind..I get a little too carried away. Goes back to my high school days in Math club. Time intersection physical mathematics...Hypercubes, turning basketballs inside out, passing a door thru it's keyhole, walking through walls, you know... noneuclidean geometry.
