Hm.. It's definitely not my area of expertise, but I don't think it's too 
difficult to create some mechanism that for each moment outputs the 
horizontal position and vertical extents of the score. I don't think it would 
be too difficult to add similar metadata to midi either (except that it 
probably requires that midi is cleaned up). I guess the most difficult part 
is to import and combine all lilypond output into a nice gnash animation, and 
to design that animation.
