It will be well into the future before we see this on a regular basis for day time ops around the US. The FAA just doesn't have the ability to control air traffic like that when the airspace is busy. UPS is a great test case that is proving how well it can work, but they also are testing ADSB (or however it's supposed to be written) to make it work. Unfortunately, until we all have ADSB and the FAA is thoroughly modernized (good luck with that) it isn't going to be something we do here.
