This is how I watch the Winter Olympics: I open the NBC Olympics app on my iPhone, and turn the WiFi off. I enter my friend's cable account username and password. Over the data link NBC can't determine if I'm really a paying cable customer or not. I turn the iPhone WiFi back on and I watch the Olympics on my TV using Airplay. The app remembers my information, so next time it immediately starts streaming without asking for user my name and password.
