Bluetooth PAN server in MacOSX 10.5

Just played around with MacOSX 10.5 on an external drive, when I found this gem, that I have been looking for a long time: when you access System Preferences/Sharing, you can turn your Mac into a Bluetooth PAN server. Great when you have a fast WWAN connection through HSDPA/HSUPA and want to share it with some Bluetooth devices.
