There is also plenty of space in the conduit running between boxes. When we looked in there was a lot of dirt but the cables themselves took up only a small fraction of the entire space in the tubes.
If we were able to make use of the existing conduit I can still see a problem. I don't know exactly how we would be able to get from the inside of the box out to each home. There are lines going out to each home but I figure we'd probably need to dig something new ourselves. This could pose problems as well because most of the drop boxes are in driveways.
It's certainly a possibility to consider - assuming that we could get permission from France Telecom.
