wanted: wireless magic tricks

When we ran a T3 satellite link we installed Mentat boxes on each
end. See: http://www.mentat.com/skyx/skyx-nasa.html for a nice
comparison of TCP vs their SkyX protocol. Bottom line: it works
and no user had to change a thing in their TCP stack. Their
product goes up to T3 speeds, though. If you have access to the
end devices and want to "tune the stack" to achieve full thruput
via high delay links see:
TCP Tune | PSC

Right. Lots of these boxes exist. I would encourage folks to
consider the implications of these boxes before putting them in
general purpose use, though. They are sometimes OK, and sometimes
they may not be. See RFC 3135 for a discussion.
