I have a question regarding this as well.
I have mapped the arrows and the 1 & 2 buttons for Openarena which makes the game very playable I must say.

However how to get the accelerometer to work with the wii.
I want to use the accelerometer as well as the buttons.
so for example for aiming in this game.
or for driving in a emulator?

Is this possible?
I also suggest that the developer of this app, great a gui for the control mapping. That way things are much easier for everyone.

Otherwise great app so far thanks :-)
