Don't know. Pixologic is still working on add-on scripts for ZBrush3 (many of the ZBrush 2 scripts won't work).  I've no clue about Skymatter's plans for Mudbox and the device.   

If it makes ya feel anybetter, we recently added support for it in Poser though. :)  Not quite the same kind of app I guess, huh?   Doesn't the SPace Navigator site list what apps are currently compatible or is that not the case?
