I have written no code, only used these programs at the same time.
First I connected my n810 to pc with bluemaemo. Next I installed wiicontrol, and connected wiimote to n810. In wiicontrol, I tested Gamebad, Browsermode, Snes, and Gyro. All but B trigger gave input to pc in the form of certain Keyboard keys.
I successfully mapped keys for emulators on my pc. I used Dolphin, and Snes9x.
Couple of issues: It doesn't seem to understand two buttons at the same time. Also, I think it would be neat to get B trigger and Gyro to act as touchscreen dragging, and a as left click, So as to use my wiimote as a mouse through my n810.

So if anyone has the time, and knows what they are doing, is it possible, to make multiple keys work? And get wiimote to take advantage of the touchpad function on bluemaemo?
Also, getting the nunchuk to work with wiicontrol would be cool, but one thing at a time.
