I want to connect a Wiimote. I'm running natty and would like to control an audio-player with my Wiimote. Is that possible?
Edit: Rinzwind tipped me off on a launchpad project called "wiican". Apparently it is implemented as an indicator applet and allows to customise your wii-actions. You could bind e.g. amarok -t to a wiibutton.
You're in luck, and you don't even know how much. It took me a while and a bit of research but: I wrote a script to do just that a while back. It works with Amarok and Totem, though it could easily be modified to control other players (provided they have a command line interface). Give me a few minutes to write a few comments together. Then I will edit this answer and post it.
You will need python and python-cwiid /
sudo apt-get install python-cwiid installed. You can do that while waiting.
Below is the script. Just run it in a terminal.

"""A Wiimote script to control totem and amarok under Ubuntu.
Provides a rudimentary interface to:
-Check battery status of the Wiimote.
-Switch an led on the Wiimote.
-Start Amarok.
-Pause/contiue playing.
-Skip to next/last track.
-Control the system volume over pulseaudio
Needs the package 'python-cwiid', 'amarok' and or 'totem' to be installed.
