Google could use this to bootstrap a FON like worldwide network. Have an additional option in the settings for "Make this network part of Google Free Wifi" and then any android phone anywhere can connect seamlessly to the network. If you change the security settings they are immediately updated because you also update them on your own phone. At least for networks that are already designed to be public (e.g., coffeeshop wifi) this would be awesome. For my home network I'd have to first setup a second SSID myself that I firewall from the rest so that I don't expose all my wifi devices to any passer by. That bit isn't very user friendly.
