Please, let me know you findings, I am very interrested, also on the
source code. How do you plan to do this?

Seams trivial to write an interface for the magnifier to be
controlable this way.

This will need to be known through many people developing

So even the source of the image to be enlarged could be customizable
(the desktop, or the contents of a software window).
