There are several companies who tackle this problem. Obviously, solving a
problem
by a hop-by-hop special optimizations is a very good way to utilize each hop.
So they do what is called today "spoofing" - cutting the TCP session to 3
different segments,
(more accurately - 3 different sessions) where the middle segment is the
satellite link.
Usually, on the satellite segment they use a dedicated protocol.
One of the companies I personally know is flash networks
(http://www.flash-networks.com),
their homepage is quite good.
