so with this description a satellite system that uses 2 proxies
on each end of a satellite link and does its own protocol between 
the proxies is also compatible with the e2e argument.
so long as the bits comming out on the proxy1---server and 
proxy2--client are the same...?
the only gurantee is that as you say.."the bits get delivered 
as sent......and the bits are unmodified..." 
so inbetween the 2 proxies compression etc...are all completely valid?

If as you say, the e2e argument does not say what happens inside the 
network, then I guess the above would hold true....
