I'm thinking that you run the risk of turning players away from certain games by how you define the NAP restrictions up front. Maybe that's the point? But I don't know if you want to create this kind of schism amongst the smallish community.
I think you're better served by reminding everyone that they need to take particular care in the individual NAPs they set up during the game. I see this as a federal vs. state issue, where the host is the fed and the players are the states, and personally, I'm not that interested in having my rights dictated unnecessarily to me
