A brief description of how PersonalTelco will conquer the world 
Phase 1.
Get as many AccessPoints (they will not be inter-connected to start with) up as possible. Help people make sensible choices about hardware.
Phase 2.
Use those AccessPoints to to start building local communities (eg. sharing with neighbors who have convenient LineOfSight). Each community should be autonomous (this is key). Currently the plan is that each community will have an access point, a CaptivePortal (probably a *nix box) and an internet connection. In the longer term they will also have at least one wireless link to another local community.
Phase 3.
Start building wireless connections between communities. By this point we should have a better feel for what's feasible and what technology works well for us. Our original intent was to just let the network mesh however was convenient, further thinking has revealed that we're not too confident in this plan so we have started talking about setting up regional aggregation points with higher quality gear.
