Same functionality and same limitations as xpadder.
We can't have the space pilot pro movements without mouse cursor movements, making it almost useless as soon as you leave the viewport of any unsupported 3d app because yo ustart to grabe and move things in the ui. :/
The driver needs to lock the current cursor position before 3dx interaction and restore it every x ms. At least that's what I think, I'm taking zbrush for example you can't have panning without starting to zoom (with the zswitcher plugin).
