>Ethernet cable of 1/4 - 1/3 mile (400-530 meters). Would that work?
No. I've gone 275 meters with 10baseT-HDX (half duplex). It won't
work at 100baseTX. The official maximum ethernet length is 100
meters. I've also gone about 275 meters with coax cable using RG-6/u
and 10base2 (cheapernet). However, I'm fairly sure there is some
manner of timing limit at about 400 meters of CAT5e and coax. It's
easy enough to test with a 300 meter roll of CAT5e. Just put
connectors on both ends and try it. The biggest headache will be be
forcing the speed down to 10baseT-HDX.
You might be able to make it work with an ethernet switch at midpoint
acting as a repeater. You can power this switch with PoE at 48vdc if
local power in unavailable. I don't know of a product that will be
suitable and cheap but can do some digging.
There are also ethernet line extenders that will work out to several
km. See:

etc. The catch is that they are very expensive.
