Gigabit Networks at Home

I have been following Scott Hanselmans notes on his Ggigabit network. At first I considered it no big deal, but after reading this Wiring the House for a Home Network I am definitely going to look into it. I thought I was doing Ok (I get about 7 Megabytes per second) but apparently I am off by a factor of 10. Need to check the wiring and the frame sizes. Unfortunately I can not do anything about the Vista SP1 issue until I can get on a beta or something.
