The Bluetooth To Internet Utility allows you to share an Internet connection from one Mac to up to seven other Macs or Palm devices that have Bluetooth hardware. You can run network programs, play games, or anything you can do with a wired connecton.
The utility starts a PPP server over a Bluetooth port. The client Mac or Palm then connects to the Mac using PPP. The server Mac then shares the Internet connection, using Apple’s Internet Sharing.
