two high-level questions:
- do you have a list of devices you've tested on so far that provide useful
  data?
  we need to figure out how to handle devices that have invalid ranges, such
  as the T440s on my desk. Range claims 0..255, the max I can trigger with a
  finger is ~10 which atm translates to 0.20mm or so. I can get up to
  about 20 if I put my whole palm down.
  either way, we need some strategy in place to deal with those devices and
  figure out how widespread those are.
- do you have client-side code that makes use of these properties yet? I'd
  like to have a look at it.

Cheers,
   Peter
