"A French telco is to assess the feasibility of setting up a city-wide public Wireless LAN (WLAN) network for Paris. The company, Naxos, is to piggyback off the data networking cabling system installed in the Paris Metro to deliver Wi-Fi access points above ground in a year-long trial. The pilot, dubbed WIXOS (Wi-Fi eXtensible aux Operateurs de Services), is limited in scope - 12 locations along the Bus 38 route, which connects the Gare du Nord and Porte d'Orleans, the two main rail termini in the City. But if it all works out, Naxos will roll out Wi-Fi throughout the city, underground as well as above. Some of the big Metro stations could have up to ten access points on each concourse ... It could be pie in the sky. But Paris, compact and with a ready-made networking infrastructure supplied courtesy of the Paris Metro, means that there should be little in the way of technical barriers."

Salon: Paris becoming world wireless leader
There's a great spot in Manchester, down by Castlefield, whereby you can see a visual history of the layers of transportation of people, goods, and services. Down by Duke's 92 pub, you're on the early Victorian canal side (no doubt based around medieval packhorse routes), with a late-Victorian rail arch above that, then a mid-20thC electric railway line above, then the late-20thC Metrolink electric tram network above that. With power lines and telephone cable above it all ...
I like the idea of wifi access being pinned around the existing Metro stations in Paris - as well as being thoroughly pragmatic, it reinforces the ideas of nodes and networks, of transit and transport, of change and flow.
