Anyone else getting hungry now?  I wonder what effect a nice marinara sauce would have...

Somehow I'm CC'd privately in this discussion, of impedance of a DSL
6MB/s line made of wet salty starch. But I'm a BSEE engineer, so there
is a theoretical answer. There's a practical answer, that's likely
harder to describe.

Fifty years ago, I solved a similar problem, in showing how 9600 baud
communications could be done on 250 feet of twisted pair telephone
cable. PhD's said it would not work. I did not an analysis. I hooked up
the wire spool between two terminals and started typing.

I don't think a wet-pasta analysis is worth bothering with. It's simply
a happenstance that the DSL traffic happened to *succeed*. "The amazing
thing about a dancing bear, is not how well it dances, but that it
dances at all."

So enjoy the result and don't fuss about the solution.
