new property for soft bodies

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.
