This all sounds nice, but as a General Contractor, builder, and developer,
who has done lots of pre wire in his 30 year career, I can tell you that
trying to save a couple of hundred bucks by pulling a less capable, cheaper
wire is just.... well, cheap. CAT 6 can be bought at Cyber Guys for as
little as a hundred bucks for a 1000 foot role.
Houses don't last five years, or twenty years,... they last fifty plus
years, and going back and pulling new wire is a major hassle. And I think
you are being overly optimistic in thinking that Cat5e will be fine 10
years from now. Ten years ago I would of thought a PII would of done
everything a office worker would want to do.
Pull 5e in your house, but if I build another house I will be pulling one
of the cable bundles with CAT 6 , fiber optic, COAX, phone, and any other
new thing I can get in there!

No, I mean period. Cable plant lifespan in the corporate world is 10
years. For residential, it's virtually the life of the house.
Talking with people on the 10GigE working group, none of them would even
consider a copper interconnect 4 years ago. Now we have one. Will it
run on Cat6 or even Cat7 (mostly used in Germany, it's very well
shielded) NO. You can't even come close to comparing Cat6 to the
twin-ax that is needed for 10GBase-CX4
There is work being done on IEEE802.3an / 10GBASE-T, which will work
over Cat 6A (not Cat6, it's the same as Cat5E vs Cat 5, it might test
out, it might not).
This standard might get ratified in 2006.

I personally don't recommend Cat 6 over Cat 5E for most new
installations. GigE to the desktop will be sufficient for the next 5-10
years. Servers, on the other hand might need more, but they are more
apt to have cable replaced. This is coming from a person who has
already deployed GigE to the desktop.
