Nope.  Just go work for someone in the generation industry for a while 
and find out the hard way, or get your ear burnt off by some senior 
technician wailing on about how dangerous this is.

Geeks have no idea of the consequences of running a wire this long, and 
I could go <OT> here and lecture for hours on the stupidity of said long 
wire, but I won't.

A wireless card is only $115, and if that is not fast enough, then put 
some fibre in.  DON'T run a long wire. (ever wondered why  you should 
stand clear of the telephone on the wall during a storm?)
