Even cooler would be collaborative filtering among pager-holders. Users can be directed to different locations based on the behaviors of riders who have historically rode the same rides in the same order.

Oh yay. A way to remove spontanaeity from an amusement park visit! I know that if this was in place when I was a kid, my mother would have brought us along the "optimal" path that had been so determined, and every trip would be the same rides in the same order. I enjoyed the chaos of trying to go everywhere at once, based on my own whims (as balanced with those of my brothers); this kind of efficiency seems antithetical to the experience. (Not that I would have minded the elimination or reduction of wait times.)
