> On the other hand, all cross-Atlantic traffic is likely to pass through the same few undersea cables, regardless of the "first 50 miles" are covered (3G/WiFi), so the net effect on snoop-ability is probably null. Wouldn't the traffic be split over multiple IPs (not all of which might be known), and wouldn't latency sometimes cause them to be out of sequence? It's definitely not as simple as "monitor this singular connection", though of course it's still feasible.
