The scheme is too simplistic.

You need to add "policy" as a template parameter to 
retain/release so that you can support different ownership 
schemes with strong typing (compile time).

You also need a policy-link between the receiver and the object.

The DIP needs to prove that the protocol can be used to 
efficiently implement the following in various configurations:

- weak-references with zeroing

- auto release pools

- unique ownership

- optional locking and transfer between threads

- wrapping of foreign objects that have their own RC scheme
