moving is already a cheap operation because only the parent node id changes.

copying in JCR is fundamentally different from subversion. in subversion the 
uuid of a resource does not change when you do a copy. In JCR a copied 
referenceable node *must* get a new UUID. Therefore copy in JCR is potentially 
costly and cannot be implemented in subversion style.
