Sports Bar Audio

As I watched the Broncos-Chargers game last Sunday at my local Sports bar, I wondered whether it would be possible to hear the game as well. It would require some integration with the satellite box, but I would think that the audio could be broadcast as a low power FM signal. Then patrons could bring portable radios with headphones to listen to the games. It would certainly be better than listening to inebriated fans rant about calls that I neither understood or cared about.
