accelerometer in neo?

[Robin Paulson]

i've been thinking recently about other applications for the openmoko,
beyond the usual phone/maps/gps/internet access, and a couple of them
require an accelerometer

i could find no mention of one in the wiki, either in the hardware
list or the wish list. does anyone have any ideas?

would this be unfeasable in a device like this for any particular
reason? size? weight? power?

thinking slightky laterally, could the vibrating battery be used in
reverse to provide this sort of data, in a similar way to using an
electric motor as a generator, or a speaker as a microphone?

if anyone's interested, one of the ideas was to enable it to function
as a pedometer
