Conventional wisdom is that one should lockdown wifi, your ISP doesn't want you to share your connection, that person checking email outside the coffee shop ought to be arrested. Here is an alternative model: "BT will encourage its three million broadband users to pick up a FON router and start sharing signals. The router provides two channels: one for public access, and one for access by the owner. The public channel is bandwidth-limited so as not to disrupt the user's own connection. Other "Foneros" can access the public channel for free, while non-Foneros can pay a few dollars a day to use the access points.""
