Its no different then you going to your local cable company and buying space on their leased access channels then running ads for Satellite TV. Its your time you paid for it, you can run what you want on it as long as its legal. And NPS is legally selling distant network services as it has been doing for YEARS. Just now however they are going to gain a large number of folks who are Dish Network customers as well (as they are going to gain Sky Angel Customers)
Smart business move from NPS and all LEGAL!
Eh, what do I know about legal standards, I'm only a lawyer in real life. Let NPS put any other programming on E*'s transponders and they'll be fine. DNS by and through an E* asset, and its toast. Your bias won't make it otherwise.
