I'm guessing someone's come up with the idea of a "health monitor" for the checkpoints, similar to the idea for traffic reports that radio and TV news stations report. Would it really be that hard to implement something of the likes for passenger checkpoints?

You could get as sophisticated as having cameras mounted at each checkpoint and then a group of people remotely monitoring checkpoints throughout the US. Or on the other side, have something as simple as a status page someone can update on a 5-min basis. Have perhaps 5 buttons, 0-5 min wait, 5-10 min wait, 10-20 min wait, 20-30 min wait, 30+ min wait. All of it automatically updates to a main site.
