It seems you are from north of the border, lucky for you. I have been looking into this gear from http://www.cambridgebroadband.com and they calim that they can go 20Km without a repeater. You should find someone between the city and the campus that would not mind getting free broadband for having a repeater on their roof. I cannot use it here because it operates in the 3.5 - 3.8 Ghz range and the FCC has not approved that range here.
