I can't speak to most of those issues, but piezoelectric actuators can move precisely on nanometer scales. They control the positioning in many modern atomic force microscopes. So it seems plausible to be that they could achieve very fine control. Dealing with noise seems like the harder problem. Perhaps embedding sensors in the glass could give you real-time adjustment feedback.
