IMHO, this would be a nice addition to luatex, pdftex, and xetex.

Very interesting, thanks!  Note, however, that we don't generate the
small snippets with pdftex/xetex/luatex but directly with ps2pdf from
a PS file generated by lilypond, so we fortunately don't have to jump
all the hoops you are demonstrating here.  In particular, we access
all glyphs with the `glyphshow' operator, thus avoiding the need of
map files completely.

This we will certainly need.

As mentioned in another mail, this was a problem with the XeTeX
support in texinfo.tex, now fixed.

Yes.  Maybe someone has time to add this to the various TeX flavours!

Again, thanks a lot for your tests!
