Now that the buzzword of convergance of WiFi and cellular is going full steam the question now seems to be 'who owns the talk time?'. If I have a cell phone and am using the cellular network, it's easy to bill me for the talk time. If I'm at my home or business using the WiFi link, it's my internet connection and WiFi being used. So the telco's are fighting over how to bill people for the WiFi portion of thier calls. Various methods and camps are being setup that offer different levels of cost and features, but there seems to be a standards fight in the near future.
