FreeFi will overlay advertising on Wi-Fi free hotspots; The press release claims FreeFi is the first Wi-Fi ad network, but it's only narrowly the case: DotSpot launched in March and both builds out hotspots and then sells advertising on them. The FreeFi site makes it clear that FreeFi is a software gateway overlay. The FreeFi system uses a Web-based advertising bar that apparently a user must agree to open in order to gain access. It says it doesn't rely on spyware, popups, or other annoying tools. (The FreeFi logo cleverly incorporates the open Wi-Fi hotspot warchalking symbol.)
