As long as there is no earth voltage difference between the houses it will 
be fine.

I ran a long ethernet to a friend's house several years ago and we found 
potentials exceeding 50VAC to his equipment earth from the cable after it 
"bit" him. There turned out to be a corroded neutral connection in 
underground power cables from the street, which was fixed quickly, but it 
still serves as a warning.
