Wiimote as an accessibiity enabler?

The picture of The ThinkGeek WiiHelm I jokingly attached in my last post has suddenly made me wonder if the Wiimote could be a very cheap accessibility enabler for people with some specific mobility limitations... The Wiimote can interface with computers, but I don't know if its sensitivity is low enough.

I'm posting this just because I didt not get any obvious google hit on this.

Update: This post has reminded Josep Maria Ganyet about a video of a Wiimote being attached to a spring horse, turning the mostly static experience of driving videos into a sort of motorcycle simulator. Nice idea.
