This is a very interesting study.  I visited a Native Canadian community outside of Calgary over a year ago and they were paying huge costs for Internet Monthly fees. Sadly the local Native Band was responsible for the ISP and they didn't want any competition with a community network project despite over 300 members of the community were living in temporary housing due to a major flood.  I think we need to aware of the inherent resistance and power blocks in communities that undermind cost saving efforts for community networks.
