Reverse tethering? Mac Pro? Bluetooth? AirPort?

[metadog]

Hi! My desk at work is basically in a cellular dead zone. No Wi-Fi either... But I was wondering, I have a brand new Mac Pro with bluetooth capability and AirPort. Is there a way that I could have my Droid 2 connect to my Mac and use its network connection to access the interwebs? I'm not worried about making calls...

Thanks!
