Another bike-up-the-hill idea would be to take the basic ski t-bar/pom approach.  I have wondered whether a simple continuous rope belt with loops or knots to hold would allow a reasonably experienced cyclist to get hauled up a hill.  It would need to move fairly fast to allow for stability, but that would also make it fairly attractive as a commute-assist.

However, there is a project being built of a nature you didn't mention : a bicycle tunnel. The same Croix Rousse hill has a road tunnel running under it. A second tube was required, to bring it up to modern security norms; this tube will be dedicated to bicycle, pedestrian and bus traffic. It's to open in 2014.
