So, I was musing about just how many routers FON would need for total world domination, I'd already sussed out the a million routers wouldn't go far, and then a guy does the maths properly and comes up with around 5-600 million routers, woah! Sure there's holes in the theory, you don't need coverage in the middle of a desert, but that's still a hell of a lot of kit.

In other news, Portugal is now bathed in a 3G signal (HSDPA) at up to 3.6Mbps. Hey that's a little simpler than relying on 888,219 routers to be all working, and you'd be able to stay online whilst on the move...
