That's not my point. I know that font loaders exists. We have
luaotfload which can be used with latex + plain tex. There is the
font loader code of context. There is the generic font loader code
somewhere deep in the context tree. I have tried to use all of them:
All of them are different. None is really documentated, none is
format independant and none is written in a way which allows people
to add extensions or improvements.

It will be imho impossible without a sound starting point and real
contact to the developer of luatex.
