Sounds interesting!
There was a postdoc advertised in my department recently for doing "visually guide navigation" with a mobile robot; wished I'd worked harder to finish my thesis so I could have applied for it... (but then I'd have less time for LaTeX:)).

No, the Imagemagick comparison is essential for automating it -- for unicode-math there are over 100 different tests and you certainly don't want to have to flip through them all every time you send out a new release :)

Well, I can't say it's a top priority in terms of being necessary, but it will be needed sooner or later. If we could recruit people to create tests for us, moreso the better. (Creating the tests is easily the most time-consuming part.)

I'll see how easy it is to adapt my unicode-math Makefile for fontspec (should be easy enough) and send out a request for contributions.
