With Fon, a Spanish upstart, you can use other user’s internet connection for free or for a lower fee than normal hotspot providers. However the best thing about it is that you can make more moolah out of your own internet connection (to offset your internet bills).

With the proliferation of Wi-Fi hot spots, it has become increasingly convenient to tote around a laptop, sit down at a coffee shop, airport or hotel and pay for a wireless, high-speed connection to the Internet.

Fon, a two-month old company in Madrid, now wants to create a worldwide Wi-Fi network out of all the Wi-Fi connections people have in their homes. Much as you might pay to connect to a T-Mobile hot spot at a Starbucks, with Fon you could connect to somebody’s home Wi-Fi connection.

Fon, which was created by Martin Varsavsky - an Argentine who has already founded several successful Internet companies, like Jazztel and Ya.com - has signed up 3,000 users since November.

Varsavsky said in an interview that he hoped his company would have more hot spots by the end of 2006 than anybody else. “That is very ambitious,” Varsavsky conceded, “but we already registered 3,000 people in two months, and T-Mobile, which has the biggest network of hot spots, has 24,000 and it took them four years. With Fon, the potential is enormous because every person who has a Wi-Fi connection in their home can quickly and easily become a hot spot for others to use.”
