Maybe cut a slit across your concrete driveway with a diamond concrete saw and drop fiber in, seal with some polymer afterwards?

Yeah, it'd have to be something like that, and nomatter how well you did it, it'd be noticeable.

Fortunately, (as I mentioned in another thread,) I got a powerful enough point-to-point wifi connection to blast through the stone walls and get decent results.
