The other big problem with long runs of Ethernet is the increased likelihood
of equipment damage due to lightning or ground potential differences.  Near
strikes can/will blow up the phy or magnetics on copper Ethernet interface,
and the longer the run, the more energy will be coupled from a strike, and
thus the more likely that there will be damage at either/both end.  Mike's
right, fiber is the way to go in a situation like this, even if the maximum
distance limitation for copper wasn't an issue.  Media converters to go
between copper and fiber are cheap these days, even for gigabit.
