There is a publicly available branch for download to test the new VDM sculpting feature (D17080):
builder.blender.org/download/patch/
More important information about the patch and available test .blend files can be found here:
developer.blender.org/D17080
Any testing and feedback is welcome!
There are still some issues left and more features/improvements would come in the future.
But the main functionality for the Draw brush is working.
