Yeah, it was a lot of, but I don't know how well it would work in this forum. I guess you would need a separate action stream for each team, so they could keep their moves secret. And it would be way too easy to cheat by subscribing to your opponents stream.
Besides, people playing here are probably looking for long-term campaigns, and this scenario is almost by definition a one-shot.
From what you described that's just for live play. You could probably do that here but then the threads would have to be kept hidden until the game is over.
Maybe I'm not visualizing this, what's the point of carrying on a game if only the GM and the one player can see what's going on?
In a double-blind game, you would have at least two players. Each turn, the GM would tell each player what his character can see, and each player would tell the GM what his character will do. If the characters move into line-of-sight of each other, they fight or whatever.
I think that would be a really fun way to do things but I would feel sorry for the GM that has to coordinate that game. You would need a thread for side A, one for side B, and then a shared thread for when they do have contact with each other. You would need a method of keeping them from seeing what the other side is doing unless you want to go with the honor system, and I'd worry that you would have that one person that just couldn't resist taking a peak at the other sides thread to gain an advantage.
Intelligence and communication win wars.
The setup might seem a bit tedious, but the flow of things would be pushing players right into each other. You could probably skip the thread for when they make contact, just for the sake of making sure each side is observing what their opponents are doing and actions occur simultaneously.
