In Network World they had an article for Free Wi-fi software. This software allows you to network computers wirelessly directly between the computers without having to use a router.

“We want to bring this to as many people as possible,” says Professor Roy Friedman of the Technion Faculty of Computer Science, in a statement. “When there are two computers in the same room, it doesn’t make sense that they must go out to the Internet to communicate. WiPeer’s main added value is the ability to keep things local.”

While I haven’t tried this yet it definitely sounds interesting. What do you think?
