That's the mesh-mixer method.
We just got a new software engineer at Ultimaker (he simply known as Tim). And he actually knows about algorithms and stuff. So he is looking into this right now, to see if we could implement this method in Cura. Most likely months away from actual release. But, yes, support structures is finally something that is getting attention.
Thanks for the pdf links. At first sight these algorithms look quite promising. It would be nice to know what the license situation on them is.
