Ah, the code already has partial support for accelerometers as well, so I'll try to investigate those soon a bit as well. Also, I would really like to get the keymaps to be user configurable. For now, you can also just edit the code, layout is in the form of:

This is the default mapping:
mapping={
'U': ["a Left"],
'D': ["a Right"],
'L': ["a Down"],
'R': ["a Up"],
'A': ["k F4"], # Application menu
'+': ["k F7"], # Zoom/volume +
'-': ["k F8"], # Zoom/volume -
'1': ["a Space"],
'2': ["a Return"]
}
