Well, object->parent (as well as most other similar things) are just
pointers... if you send this to another client, obviously the pointer
will be unusable there, unless you also send the *original* memory
locations of the object structs. Then, you could go through all of them and
search for one matching the original object->parent (etc) pointer.
Again, note that most of the data in the Object or Scene structs are
*just* pointers. The actual data is elsewhere.

They're linked lists, the size isn't stored. You have to walk through them
in order to find the number of elements.
