Absolutely possible. What you're experiencing is that self.PointNormal (and I think maybe all or most preexisting iceattributes) are in the object's local space always.
If you get a "Multiply vector by matrix" node and feed it your self.PointNormal and a getdata of self.kine.global into the matrix, you should be getting stuff in Global space. Beware that some of the ICE visual debugging when it comes to per-point data can appear to come from the points when that may not be the case, just because it usually draws the vector starting from the point origin when it's a per-point context. You can Build Array From Set from your attribute and visually debug the result, as it will be one big array per object instead of one value per point, and thus won't try to draw it starting from each point.
