[nSLUG] Cat5e vs Cat6

I'm glad you mentioned the max length limit. I was going to say that
regular cat5 will also run gigabit at shorter cable run lengths. I've
seen cat5 behave a bit oddly (blinking link lights) but still transfer
masses of data just fine even when the twisted pairs are mis-wired,
again, at shorter than 100m cable runs. For very short patches, I'd
bet even cat3 would work (not that I'd recommend it, of course).
