Corn IS a very interesting choice. Are you looking for a corn flavor? If so you don't want to let it ferment, corn liquor tastes a lot like vodka, cleaner but very near. Your mead may taste more like a domestic beer if not sweet enough. I would think about getting your alcohol level high enough to stop things from rotting, mashing the corn a little and boiling for a second, then racking onto it. It should give a good corn flavor once it clears.
If you want to drink the best booze, your gonna have to make it yourself.
