I found some interesting information about Google WiFi at their Secure Access FAQ Pages. It seems that Google is preparing its own wireless network all over the US, starting in San Francisco:

"Google Secure Access allows you to establish a more secure connection while using Google WiFi. By using Google Secure Access, your internet traffic will be encrypted, preventing others from viewing the information you transmit."Read more at http://wifi.google.com/faq.html.
