Make very sure you are well *isolated* (no current loops, both on the 
same phase preferably) or someone will get electroluxed.

Do a test first - run a single conductor between the two properties. 
 Connect one end of the wire to *one* PCs' *chassis* (not network card), 
and then measure the voltage difference at the other end - between the 
conductor and the distant PCs' chassis.  I think you will be surprised.

10/100baseT is isolated anyway, but not to that extent.  A lightning 
strike nearby will leave a brown stripe on the ground where your 
ethernet cable was, two exceedingly fried PCs, and two exceeding 
wide-eyed, brown-striped geeks, and probably a room with sparkles 
running around the walls for some minutes, complete with the percussion 
of 30 grams of powergel.

all good entertainment, an expensive buzz but..  much cheaper to chuck a 
flyspray can in the incinerator if you want a bit of a fright..
