Very little has changed here since the last submission, namely: using credentials for security callbacks, and replacing `Arc` with `Ref` (i.e., using refcount_t to manage ref-counted allocations). As the message tries to indicate, this is submitted as an example and WIP, it doesn't have feature parity with the C version yet.
