Google's Web site is revealing information that points to the imminent launch of a new service that would allow for secure wireless Internet access. WISPs, otherwise known as wireless Internet service providers, have been sprouting up all over the country over the last few years, fueled by the popularity of Wi-Fi, many of them free. Google's entry into the space would pit the search engine giant against commercial WISPs such as T-Mobile, Boingo, and MyConnect. An early rendition of Google's new service, currently dubbed Google Secure Access (beta) is available in San Francisco's Union Square area. The new service will provide users with secure VPN access.
