I'll correct my own mail.

We want to handle 4 types of accelerometers:
- quaternion sensor IIO with ring buffer (the type present in some
Yogas)
- accelerometer IIO with ring buffer (the type supported by
iio-sensor-proxy and in the Yoga as well)
- polling IIO (the type used in cheap tablets such as mine)
- input device accelerometers (as present in the WeTab)

Given that range of devices, it makes less and less sense to me to put
it in systemd. I think that I might start thinking about a D-Bus API,
and expect interested desktops to use that instead of adding hardware
specific code in systemd.

What do you think?
