If the "routing" was all based upon a connecting a circuit from a dishy to a ground station, and they never look into the packets, then it sounds like bent pipe to me. Even though the specific physical path would change every ~15 minutes. One could do this with a variety of technologies, but I'd probably use MPLS. OTH, if a dishy could be moved from one ground station to another, then that's a different matter. > But I will say that since they NAT the connection at the ground station (or > Internet peering point), and not allowing dishy-to-dishy direct I don't think that the l3 NAT44 is particularly relevant in this case. One could easily allow for dishy-to-dishy "behind" the NAT, but it requires an L3 decision point before the NAT44/Internet-Peering-Point. I thought that there was many with working IPv6?
