"....a couple of years ago, Budweiser started selling a device to bring the experience into Canadians' living rooms. The product is about the size of a roll of paper towels and has a red light and a horn. The customer picks her favorite team using a smartphone app. Then every time her team scores, the light turns on and the horn sounds, making her feel like she has rink-side seats at the game."

They were talking a while back about putting tiny microchips into the ball that would take any guesswork over whether the ball crossed the plane of the goal line or not out of the equation.

If they did that, then something like this would be very possible. Though it would need to be calibrated to not go off after plays, or on touchbacks and such.
