Where did the word "single" come from, given he had an "s" on gateways? Replicate them across POPs. Having lots of routers accessible from a small number of machines, which are (relatively) widely accessible but can be firewalled to hell, seems a better option than having lots of routers accessible from a large number of machines (esp. ones outside ones own administrative domain, e.g. home machines). YMMV. [no I don't think they need the other pixie dust stuff on though]
Well, either you have one per POP (and that, as Randy Bush points out, can be quite the headache in itself), which is still a single point of failure for that POP, or you're advocating that the routers be reachable from the magic box at *any* POP (which is right back into the "large number of machines" issue....) In any case, the concept is merely a workaround that doesn't actually fix the real problem - right up there with arguing what color band-aids to use on a hemophiliac....
