If I remember correctly shielding is a two way thing, basically you are running a potential 40ft radio aerial in the latter case. If you have a lot of cables or have anything which is sensitive to radio emissions close by, Cat 6 starts making sense.

There are two ways to reduce interference to & from a cable. Those are shielding and twisted pairs. UTP cable, including CAT 6 relies on twisted pairs to reduce interference. Unless the twist rate for CAT 6 is significantly more than CAT 5, there will be little difference between the two for interference purposes.
Exactly so. Also this 40 foot figure bandied about here totally ignores the fact that entire buildings are wired with CAT5 runs much longer than that with no problem. -- _____________________________________ John Andersen
