The receiver is the one that informs the sender how large of a window it
can accept, so it can be practical for a subscriber installation. It
wouldn't be a good idea to park a bunch of servers behind one of these
links, but any receiving node that set its TCP receive window to 2x the
byte/sec capacity of the link should see decent throughput.
