Thanks for making this clear.

Are there any plans to replace libhnj by a pure Lua implementation?  As 
long as hyphenation is hard-coded in C, it remains a black box for the 
LuaTeX user.  As far as I understand it, there is no easy way to monitor 
the hyphenation process other than writing your own hyphenation module, 
messing with nodes, and hook that into the hyphenate() callback. :(

That's what I'm doing, currently (outside luatex).
