The missing link here in my mind is what is on the other end of the 900Mhz link? Someone has to have an internet connection on the other end of it. It is not clear who would want to provide that and pay for it or how many users you could get on that link at the same time across the ISM band which is inherently noisy because cordless phones, baby monitors and all kinds of other unlicensed devices use it, 2.5 miles seems pretty optimistic. The best anonomizer I have found is simply finding an open WiFi hotspot and connect to it remotely. I live in a fairly urban area and if you use a directional high gain parabolic antenna you can connect to any number of open hot spots from afar and it is almost impossible to figure out where you are unless someone has a triangulation equipment set up ahead of time.
