andreas: I didn't say there wasn't others way to do it, but that's not a very practical way and it'd cost a lot of money to do it. You could get by with one monitor if you shut the screen between moves.
As for logging on to the game site at the same time and playing, I tried this with my brother on IYT a couple years ago. It wasn't as good as I'd hoped, but it does work. It also means you need internet service and two accounts on a game site that has Dark Chess. And kibitzers still can't follow the game in progress.
I'll just keep asking anyone that can program if they can do it. Eventually someone will, or I'll have to learn how to program it and do it myself. Such a set up would have other uses besides the playing of Dark Chess. I'd be surprised if roll playing games aren't done this way. I've seen arcades that have car racing games hooked together in a similiar manner.
