Luigi and Hans will correct me if I'm wrong here, but I don't believe that this is the case. The LuaTeX engine contains a built-in "fontloader" module, which is indeed based off of FontForge. In the past, the ConTeXt/luaotfload font code used this module, but at some point, this was rewritten in pure Lua, so the current ConTeXt/luaotfload font code does not use the "fontloader" module at all. The "fontloader" module couldn't be removed due to backwards compatibility concerns, but as far as I'm aware, nobody uses the "fontloader" module for anything right now. Thanks, -- Max
