And I just did it too. I paired the ipad and imac via bluetooth, then in sharing on the imac I clicked 'Internet Sharring' and NOT 'Bluetooth Sharing'. Under 'Internet Sharing' on the imac I checked 'Bluetooth PAN'. Then on the ipad I just have bluetooth on & connected and open a browser. Voila- internet connection of imac passed to ipad over bluetooth, saving me from going two rooms and a hall away.
