Transfer rates significantly less than 10 packets/sec are relatively
easy to achieve if you have a sufficiently lousy Ethernet interface
(e.g. 3C501) and offer a big TCP window to a fast host afflicted with
the standard 4.2bsd TCP retransmit algorithm.

Leo is describing a tuned situation with good hardware.  Your prophet of
doom has probably seen a pathological situation with bad hardware.  Writing
your own relaible protocol on both ends of the connection is a lot of
effort.  Perhaps your prophet of doom would be appeased by the use of one
of the freeware TCP/IP stacks, which would allow you to tinker starting from
a working baseline....
