I'm open to everything as long as it is stable and usable ;-).
Personally I think that a dedicated extension (.luavf, .luafont,
.lvf, or whatever) and a kpse-search path in \fonts, e.g. fonts\lvf
or fonts\luafont would be the best. This would prevent arbitrary
files to be loaded as fonts.
A year ago something like "\font\test=file:myvirtualfont.lua" worked
with context, but the lua-files had to be in the standard lua-search
