Wow, that's pretty interesting. They're talking about some pretty small numbers for resolution though. For consistent parts it would make a huge difference. More random parts like sculptures may not benefit too much but on a lot of my prints they would benefit from variable layer heights. I'm thinking of the top surfaces on things like the bench or Marvin. I've not attempted it yet but I might try some small bits with S3D. I think (?) you can define different processes based upon height. Anyone know what the XY resolution is for the BB?
