I know I'll never find it again, but a few years back some engineer
type from one of the modem companies wrote an article for either
Midrange Computing or News/400 on the physical limits of modems. As
I recall, the physical limit on two wires using any method was 33.6
which was reached by the amount of electricity you could shove through
a very thin wire. The article explained all the math equations that
prove this out.

In a large account that I did some work for, the question came up
about "just" how fast their lease lines were running. We finally
came to the conclusion that there really isn't a sure fire way to 
measure through put on a comm line with any software tools.

The phone company remains the only source of this information and
I could not find a proof postive way to determine if a V.35 line
was "really" running at 512kb.
