How can I use a Wii remote as a remote control for Keynote on my mid-2011 MacBook Air? I have a Wii Remote and a mid-2011 MacBook Air. What do I do to pair the Wii remote with the Air, and what software can accept input from this Bluetooth device and send it to Keynote?

I'm looking for much more than a link to a piece of software. What software do you use, how do you go about setting up the pairing, and how do you go about using the Wii remote?
I believe that you'll need to download Darwiin Remote form here: http://sourceforge.net/projects/darwiin-remote/. This software will allow communication between the Wii Remote and your computer.

I haven't played with this for a long time, but I believe that when I did this app allows the Wii Remote to act as your mouse and provide direct interaction with the system (I used a candle to provide the required infrared source for tracking).
