Our house has 3-conductor wiring for the range and dryer. Would it be OK
according to the NEC to run an additional (green) conductor alongside
the existing wiring and replace the receptacles by 4-pin ones? If so,
what gauge? Or would the existing wiring have to be replaced?

Just put 3 wire pigtails on your appliances and get on with life.

Yes it would be OK, but it's not necessary. (a #10 wire should be
adequate for both if you do it anyway) You should not have to replace
the old wiring, but that kind of depends on whether the existing neutral
wire is insulated.

I realize that it's not *required*, but I was thinking that since our
new range comes without a cord, I might as well buy a 4-wire one and
upgrade the house wiring at the same time. And I assume that the Code
change was motivated by safety considerations, not just a desire to sell
more copper.

No, it's not. All conductors for a circuit are required to be in the same
raceway or cable. [2005 NEC, Article 300.5(I)]

That's true. Code permits connecting new appliances to *existing* 3-wire
circuits, but prohibits installing *new* 3-wire circuits for this purpose.

If it were me, though, and it wasn't too much effort or expense, I'd pull new
4-wire cable.
