I did not read the source story but what I had in mind was running a fiber cable through existing gas pipes, not transmitting an actual signal through the space inside the pipe as people seem to think here. Did I miss something?
The BiG (or BOGUS) proposals to date don't include fiber. While fiber in the gas pipe might make some sense in more urban environments to get to the building, in more rural or suburban environments it's hard to see the savings vs. burying fiber. Additionally, it would need to be bypassed around valves, meters, etc., which would be quite expensive.
