I still think there will be an issue of arbitrariness.
No matter how right MLB could make this system, there will still be complaints. Maybe they would be valid, maybe not. I just don't see a way to make the umpiring of a game "perfect" in the eyes of players, management, coaches or fans.
Would such a system make the calling of the game better? Dunno.
But it's certainly something I'd want hard evidence of, through at least a couple years of testing at the minor league level.
