RE: [10GBASE-T] RE: EMI Discussion

Hi Geoff,

Good point of clarification.

I was not directly involved in that effort. At the time I was working on
802.4 (rf modems,CATV,etc) but I know a number of the folks who worked on it
and actually have an original copy of the massive binder full of work done
by Bob Conte et al. It was an impressive effort and I think we are looking
at something similar here.
