I say again: ICMP replies can come from /any/ hop along the route, not 
just the first or second hop.

Exhibit A: traceroute.

Also... At one point we had the misfortune to use a satellite-based 
Internet connection. The /bandwidth/ was fine, but latency was about 200 
ms to ping Google. They had a big expensive HTTP proxy cache on the 
local end to try to hide the latency - which /obviously/ had absolutely 
no effect on the huge array of non-HTTP services we need to run... But 
hey, what do you expect if you try to use a residential broadband 
service set up by three blokes in a van when what you actually need is 
an enterprise-class connection?
