sb->lcom : Center Of Mass .. might be used to create loc IPO sb_>lrot : is a matrix[3] esitmates the roatation in world coordinates .. might be used to create rot IPO sb_>lscale : is a matrix[3] esitmates the scaling in world coordinates .. might be used to create scale IPO (no python for that yet .. but may be matt has mercy on me ) can be cropped direclty in soft body module by function static void SB_estimate_transform(Object *ob,float lloc[3],float lrot[3][3],float lscale[3][3]) The targets lloc,lrot,lscale should work to be NULL, just in case you don't need it. However i'd prefer if they were accessed via properties which should be calculated automagically if sb->solverflags & SBSO_ESTIMATEIPO is set, like they do in draw_sb_motion(..) in drawobject.c added static void draw_sb_motion(Scene *scene, Object *ob) to drawobject.c for debuggering (had a hard time with destructive matrix operations ) if it causes any trouble with your build on any OS make sure to comment that away. softbody.c and DNA should compile fine in any case.
