 Hence the following is true:
 * Have a `ResponseFrameCreator` to generate frames that are not complete entities
+* Provide a `response()` method in `Frame` to generate a response frame or `ResponseFrameCreator`.
 * Use flags within `Frame` and streams to indicate `primary` vs `reponse` frames.
 * Response frames accumulate changes into a primary frame awaiting creation.
 * Non-response frames (primary frames) generate `onFrameSet` events when received instead.
 * Allow for security by filtering primary frames sent by wrong author.
 * Allow certain channels to be restricted to prevent change in response frames.
+* Do not allow `FrameCreator` objects for sources that are not owned (except via `response()`)
 
 It should be possible to merge multiple sources into a single frameset, currently this occurs inside the `Stream` objects through a multiplexing/demultiplexing process.
