I’m a fan of great tech ideas and startups. This week’s great idea comes from FON.

It’s idea is this: You share free WiFi with others at home/office and they share it with you when you’re on the road.

That idea is cool - in and of itself - but there more “cool” to be found. All the technology is built into a Linksys WRT54G-type router.

Ah yes, the great WRT54G. One of the best examples of the rising importance of the “Make” culture. As soon as FON reaches the tipping point hardware hacking will really lead some to the $.
