Im not too keen on having my internet go up in smoke. I could understand about going threw power lines I dont know about gas. Maybe the idea might blow up or fart on.
A lot of mis-understanding on the idea. People shooting it down more than they did broadband over power lines. To me the idea seems more feasible (gas) than over electric.
But back to the one major point, if you have gas service you probably have access to some broadband already.
