We're just using it to calculate glyph outlines with very simple
variables, not hand written metafont code, so metaprogramming and
inter-run changes won't happen.

So we can use LuaTeX's sockets to send in a simple mf description of a
glyph, with a preamble setting some variables, and see returned a new
glyph with different point co-ordinates, and no start up time cost?
