Thank you, Jonathan:

Actually, point 1 should read "TFM fileS", because in LaTeX a font
is in fact two tfm's. For example, a text in Latin script uses 
T1 (letters) and TS1 (symbols). 

This is the way to go, it seems. But just for not reinventing the
wheel, has someone worked on that?

This document is very useful, indeed. I'm reading font-def.lua

Very likely many techniques are format independent. In fact, this
is one of the aims stated in luatools.lua:

-- Although this script is part of the ConTeXt distribution it is
-- relatively indepent of ConTeXt.  The same is true for some of
-- the luat files. We may may make them even less dependent in
-- the future.

(Thank you for this, Hans.)
