I like the idea that it would also deal with rotation and scale not just the position.

Maybe something like this?

```javascript
// 1
var matrixWorldInverse = new THREE.Matrix4();

// ...
matrixWorldInverse.getInverse( parent.matrixWorld ).transformObject( child );
parent.remove( child )
scene.add( child );

// 2
parent.matrixWorld.transformObject( child );
scene.remove( child );
parent.add( child );
```
