This has been an interesting discussion.

Some years ago, while working on telecom digital loop equipment, I came 
across an REA handbook on-line that said running vulnerable conductors 
through iron pipe some feet long at a building wall reduced the current 
making it indoors; even a little inductance is effective if the source 
impedance is low enough.

And it might keep the fire from spreading if those wires exploded in the 
pipe!
