So you don't just outfit a bunch of pucks and have a camera on them. You have to outfit every rink, make sure it's calibrated right, make sure its maintained, etc.

Maybe it's just me, but I'd rather the software gets something wrong, than having inconclusive evidence and going with the call on the ice. That call on the ice has a bias, a computer program shouldn't.
I think you can get precise info as long as you know where the center of the puck is, and its orientation. You can even automate the goal light/horn in case of a goal.
I understand that you have to outfit all rinks, but it seems like we're almost there already. As far as the calibration, I think it can be done with equipment embedded in the posts/crossbar instead of equipping the whole arena. We don't need to know the puck position at all times, only if it crosses an invisible 6' x 4' rectangle.
