What would the possibility of DIRECTV setting up 10 channels (5 HD and 5 SD) of the 5 major networks ABC, CBS, NBC, FOX, CW and MyNetworkTV that would only come on during national (non-local) programming? An example would be the ABC channel being dark until ABC programming begins in the morning (such as The View) then going dark again until primetime shows begin then back to dark once they conclude. This would be cool especially if they don't carry your local channels or if your local channel pre-empts network programming for local sports and specials. Is this possible?
