Fono are trying to create the largest wifi community in the world. When you sign up you get a 'Social Router' (wireless router) to set up a wifi network for â‚¬5, and then you share your wifi with other community users and you get access to other users hotspots. So far they have grown from 2,000 users early this year to 60,000 and hope to be at 1 million by end of next year.
A great map interface lets you zoom into any country in the world to see other users hotspots. I've found a couple of people near me. I wanted a wireless router, but didn't want to pay Â£50 for one, so I'm going to give this a whirl.
