Oops...should have included this in the last reply.
Anyway, standard TCP extensions for Long Fat Pipes work well, and
are a great solution. They're not just implemented as broadly as one
would hope, yet, partically due to the usual network effects issue
(clients don't have them because many servers don't, and vice versa)
and partially because there's little demand in the U.S., the center
of the world for software development, because it's still sort of a
second-world as far as broadband deployment goes: most people still have
connections supporting only a few megabits per second or less.
(For comparison, in Japan, 45% of Internet users have fiber connections,
typically at 100 Mbps or 1 Gbps, and of the 42% beyond that that have
DSL, most of them are in the range of 12 Mbps to 50 Mbps. That means
that something like 80% of Japan's Internet users have a link at least
four times faster than the rate at which they can download from a U.S.
server without TCP extensions for LFPs.)
