If you don't want to create a context, you should not create a new world
!
Typically you should use the same world that you would use to call
RaypickContext.
E.g. :
1 - mouse = camera.coord2d_to_3d(event[2], event[3])
2 - new_center = camera.position()
3 - context = scene
5 - result = context.raypick(camera.position(), camera.vector_to(mouse))

You mean you want to get the "palm" object ? You can get it as
impact.parent.
BTW, as the parent of impact is not always the scene, you should replace
:
palm.set_xyz ( impact.x, impact.y, impact.z)
by :
palm.move(impact)
move performs frame coordinate conversion automatically if needed.

hum... maybe the formula for coord2d_to_3d is not perfect (as it is
partially empirical).
