From my understanding the fiber ring project, Yvelines Numeriques, was built to provide companies using unbundled local loops a way to connect to local exchanges. We happen to be geographically very close to the network so the civil engineering costs should be quite low to reach the fiber ring.
The other good news is our "residence" will vote next month on whether we should pay to have our roads redone. Our road is private and we're looking at roughly EUR 110,000 to redo it - spread among the residents. If the road work does go ahead then this would be an excellent opportunity to lay the fiber.
There also seems to be a lot of support from people in the neighborhood for such a project. Everyone has trouble with their broadband connections. Our DSL was out for 4 weeks straight in April and others have had similar problems. A few people in our village work in telecommunications and others have jobs that rely heavily on Internet connections. I believe that take-up could be high, particularly among the newer residents.
