I have played with it as well, hoping to use it as a mouse. The problem here 
is that the only one direction that's accelerated constantly, is the one 
downwards. 

The showstopper for me was that the stream would choke after some time. I 
think I used bluetooth most of the time, but I'm not quite sure anymore. I at 
least tried one other way of connecting, probably USB, to find out if that 
would relieve the choking behaviour, but it didn't: after a while, the stream 
would die.

I took the Openmoko wike pages Technical:Accelerometer_Fundamentals and 
Accelerometer_data_retrieval as a starting point, the test application worked 
almost out of the box (I had to change the input event to another number). 
Other people who took this code documented their use at [1]

I also took the print statements and other code that seemed not useful away, 
to see if that kept the connection stable. In case you have better luck, I'd 
be interested in your results!
