Looking for a mod

[MarioFanaticXV 0]

I often times enjoy watching games, or leaving a game running in the background as an impromptu screen saver. Sometimes I'll load something up on YouTube, but other times, I just like to see the AI go against itself without me doing anything. Unfortunately, there aren't many games that allow me to do this, so I don't get much variety. I know that Red Alert 2 requires a human player, but then I saw this video, which seems to have some sort of spectator mod which allows a third party to observe the games:

 

Assuming that mod isn't available, would it be possible to edit the rules.ini to make it so the first player starts with nothing but an indestructible Spy Sattelite and Power Plant? Or would the AI still go after the buildings even though they're invincible? How hard would it be to add "Spectator" as a faction which simply has full map coverage, and automatically loses (or wins) when all but one player (or team) is eliminated?

I'm pretty sure it is possible to make the player a spectator, but I don't know how it's done. Seems like I saw how to do it once, but I can no longer remember.

Someone has to be an observer if it's online multiplayer. Ares adds the ability to spectate an AI battle I do believe.
