Google Plans to Offer Free WiFi in San Francisco
jacksonwest writes "What's been rumored for some time has now been confirmed -- Google has made a bid in response to Mayor Gavin Newsom's request for information. The details of the bid include citywide access, for free, at 300kbps. The plans dovetail into their location-based advertising and services strategy, and come on the heels of their recent VPN service rollout."
Access point X uses ads A, B, & C. Access point Y uses ads D, E, & F.
They could also cross reference your Gmail ad hits with the WiFi access point you happpened to be connected to, and show you an ad for this tire shop, or that coffee house.
Don't have to do much more than they already are.
