Using the RemoteControl API, the first step is to get_session_key. The returned value must then be supplied with subsequent calls to the API.

1. How long is the session key valid, i.e., does it expire?
2. If it does expire, how do I know when to get a new one?
3. Do I need to release_session_key before getting a new one?
4. What are best practices when it comes to session keys?

Thanks!
