With regards to exempting services from data caps, it's called "zero-rating" and as far as I am aware, the net neutrality laws we have on the books don't mention it (which is why mobile carriers have been doing it for years). I do believe that if you exempted only your own services you would start to fall into anti-competition territory though.
