DotSpot will offer free access to consumers supported by advertising; they're targeting waiting areas: The company's first push, they say, is in automotive service waiting rooms, and then into medical waiting and service areas. The site offers no public information on what the venue pays initially (they buy the access point, but are apparently reimbursed by ad sales?), how they qualify venues, nor what advertising rates are. Their site is heavy on information about how Wi-Fi works.
