His scenario isn't so much about other players playing the game directly it looks but a bit more of a council type deal where players have input on decisions and he makes the actual changes in game and processes the turns. There is a similar game that was running on the Something Awful forums.
Multi-player Aurora is pretty fun from my experience. The way we last played was where people take turns making their decisions then the GM / DM actually processes the turns and provides back a report of the actions that happened.
You can see an example in the
Children of Sol campaign in the fiction section
