Combined with IPsec on those miles, or a vetted path if it's short enough, you can reduce the amount of cable that personally-identifying IP headers are sniffable on, from a few thousand miles, to perhaps a couple of feet
According to the speed of light, anything under a certain maximum time from you is local. If all you had was a list of nodes, RTT could be used to determine a global path made up of small hops less likely to be directly monitored themselves. Hop count would rise with longer paths and performance drops... so perhaps only useful for creating local clusters. TTL and RTT above a minimum time are spoofable so not nearly as useful.
