There is no need to implement it in the luatex engine as one can hook in 
code at all kind of moments (reading files, processing tokens, handling 
nodes) and no hard codes solution will satisfy each user and can only 
lead to weird hooks into and control over such a mechanism. The only 
thing luatex can do is to provide access to internals (which it does) 
and either library or lua code can do it's work. So, one can provide 
unicode bidi support to the extend needed.

So the answer is: at the macro level (which includes the lua level).
