Part of the trick about doing cutscenes via SEXPs is that every time you do the mission things will be different. What people may be able to do is make a mission that is just a cutscene, record it using the currently unfinished demo recording system, and later play it back or, maybe, even be able to turn it into an AVI or something. (Converting it to an AVI would require a new program that could internally render the frames into a file since AFAIK the demo recorder is designed to record events that happened in the mission, not the actual screen images.) An Autopilot system for the player's ship, and that HUD toggle, might be useful in making an automated camera for demo recording. It wouldn't be an in-game cutscene, but it would look like one.
