One thing, though is I don't see the need to know when a manual transmission is in neutral or not. Just shut off fuel and let the engine turn off, whether in gear or not. Of course, depending on the engine, it could shake a bit as it comes to a stop in gear. But many modern engines aren't as shaky as older ones. Also, taking off in gear from a stopped engine still makes sense with a manual transmission. Again, it just might be a bit shaky at first.

If the system was able to know if the gearbox was in neutral, it could stop the engine at high speeds (coasting down a hill, etc.) That would provide greater FE gains than just waiting for 6 mph.
