Fantastic, this is exactly what I was looking for.
When you say it's got a specific purpose, I am looking for something that
will dynamically tune a 6Mbit/s, 220ms network link for bulk (500MB) file
transfers. Is this what I think it is, or should I be looking at something
Thanks in advance,

It got commited to 4.x and 5.x in August 2002; the sysctls were renamed
to net.inet.tcp.inflight_debug, inflight_enable, and inflight_min.
They're documented in the tcp(4) manpage. Note that it's got a
specific purpose; you don't want to turn this on by default as it will
lower the throughput of individual TCP streams to prevent backlogs and
