Cable companies vs. NFL Network

My cable company doesn't carry NFL Network either and it never really bothered me, but now NFL Network is going to start having live games. I know the Saints don't have any games scheduled on NFL Network but they may in the future and I wonder how that will work. I know right now when the Saints play on ESPN one of the local channels simalcasts the game for people who don't have cable. I wonder if the same thing would happen if the Saints had a game on NFL Network or if you don't have NFL Network you can't watch the Saints game. That wouldn't be cool.
