Google WiFi??

There is truly no end to what Google will do.  I just came across this new beta this morning for a secure VPN over WiFi that Google is offering.  It's a great idea to provide a free encrypted VPN that people can use while surfing using WiFi.  So what's the business model for this free offering?  Well, Google can see where you're surfing to I guess since you're going across their private VPN but I doubt they are going to be popping advertisements up based on that.  I haven't installed the beta yet but will shortly.  If there's something interesting about it, I'll post a follow up.  If you are interested in check this out, just click here.
