It wouldn't be that hard to simulate right now. Since you wouldn't be able to see anything the captain does, you can have pretty much anything you want on your screen. Every so often, I'll send you text messages like 'ahead two thirds' or 'steer 35 degrees'. Then you hit the appropriate key on your keyboard. If you want to be the torpedo man, it'll be much the same, except I'll message you much less often.
