Hi Linker - this is part of the geometry library that I'm using so this mechanism is available to me. (However note that PowerBoolean plug-in that you reference handles booleans in Max between polygonal objects, not NURBS objects).

But I guess implicit in when I said earlier that it wasn't feasible, was that it wasn't feasible to do with only using the minimal number of vertices that defined the outer boundary of the ngon, without adding a whole bunch more vertices in internal to the face.

The Npower mechanism adds numerous interior vertices. You don't end up with slivery quads, but you do end up with a large quantity of small ones.

I guess it would be possible to add this mechanism in, but it doesn't appear to work on NURBS "out of the box", so it would take some effort to integrate it and I don't think that it is really the type of minimal vertex result that people seem to be desiring most. So at the moment I'm not really thinking of pursuing it, I'm focusing instead on the ngon stuff.
