I'm a bit confused. What do you mean by entirey client-side
approach? Somehow the information where copy node has been
copied from must be stored in filesystem?

Can we decide which one to use, copy node or copy property?
Copy handling is another big thing left unimplemented in the
filesystem.

As I've said, I'm +1 for node property. But I'd like to
propose using flag field, instead of property field. Flag
field is internal to filesystem and it's unlikely to be as
crowded as property field will be.
