Building Community Social Capital w/ WiFi?

demosi asks: "I'm involved in the NOMAD project, which is described here. Part of the work involves determining how community wireless services can be best used to build social capital (i.e. whether something will have a positive affect on the productivity of a community and its members), by promoting communication in a trustworthy environment. We're asking Slashdot readers if they're involved in similiar projects and if they're interested in measuring the network effects of community WiFi across different countries and cultures?"
