Who would like to beta test one of my new voltage regulators?

I was just thinking...

You could control the max charging current of the alternator by monitoring current flow to the car and modulating the field current accordingly while maintaining the charging voltage.

That way you could prevent a 60 amp alternator from frying a 40 amp cars wiring system?
It would be significantly cheaper to add heavier gauge wiring in the relevant spots than to add a clamp-on current probe and the extra parts needed for a smart regulator. Current monitoring would be more useful if you were trying to do some sort of optimal battery charging strategy, and at this point I'm not sure how much demand there would be for such a regulator.
