For the $500 entry fee you would think they could provide earphones and someone would hack together an app that would let you listen through those earphones based on some sort of proximity detection. No doubt the first year someone would find a vulnerability in it and would need parallel deployment to the existing infrastructure, but still.
Would be a great idea, except they couldn't even operate WiFi with any stability (to which I heard was a LVCC problem, but I don't know that for sure).
Doesn't have to be wifi. There are many different ways to communicate. It's a matter of finding the best one. Unfortunately, the largest drawback is the potential for malicious/mischievous actors to interrupt them given the crowd. Something as simple as FM transmission, like at a drive-in, could be an option.
