Adding a wiimote in 8.10 is alot easier than the LMCE 7.10 variant.
The following link explains...
http://ubuntuforums.org/showthread.php?t=993376You can have three different ways you can use your wiimote.
...use wiimote as a mouse using acceleration
...use the wiimote as a mouse using an Infra-Red light source
...use your wiimote and IR LED pen as a whiteboard
The instructions explain swapping default left and right mouse buttons, using your Wii remote for watching DVDs, Elisa Media Center, Music Players, etc and remapping the buttons / axis on your wiimote / classic controller / nunchuck.
I tested "Using your wiimote as a mouse using an Infra-Red light source".
It worked just fine, no fuss, no muss, no files to create, minor editing.
However, you still get asked to add it as a phone.
