Apple Releases Bluetooth Software
mattvd writes "Keeping with thier promises from a few weeks ago, Apple has released thier Bluetooth software for MacOS X today. More info about the release is in the KnowledgeBase. Apple is also selling a D-Link USB Bluetooth Adapter."
"If I have a iMac connected to the internet full time, and I also have a iBook, could I use bluetooth to access the internet wirelessly from my iBook?"
No.
As mentioned on their Bluetooth page, Apple have said that Bluetooth is for wireless peripheral connection, and list it next to USB/FireWire. For wireless networking applications, such as what you're asking, Apple is AirPort/802.11b all the way.
So, basically, go buy two AirPort cards and wait for software Base Station support in OS X, or buy an AirPort Base Station. Once you've had a wireless notebook you'll never go back.
Use gNAT on Mac OS X. It's the equivalent of the old Software Base Station:s ecurity/gnat.html
