Of course, if a unit comes out with an embedded accelerometer in it then using a "slightly clunky" wiimote will no longer be needed as the source of motion data. I recently added the ability for libsixdof to control closed source applications as well as properly patched open source ones. This was mainly to let Google Earth finally take some advantage of proper sixdof devices, but it works equally well for Canola2 on maemo.

Two big features that libsixdof brings is the ability to configure what happens when the controller is moved on an axis, and how frequently that happens. So, if you don't like your images flicking past at 20 images / second in Canola, you can limit it to whatever / second. In the video, having maximum axis movement will only ever scroll 3 images / second. So when I hold the unit causing a continual next image movement I can still see what is happening and Canola2 does not get overloaded with events.

Those who have seen the maemo-mapper wiimote video, I should be able to make the panning much smoother in maemo-mapper. I need to investigate the mapper source and convert to using the "click scroll" panning functions.
