In over the board chess our county organises a tournament each year where you sign up the players get paired, arrange to play the game at their convenience with a time control like all moves in 2hrs and when all games are played you move to the next round. This is the only way I see emulating a real time tournament on brainking working. If people were prepared to play at weekends time zone differences could be worked round. You could not post a tournament and start it automatically so it would have to be organised via messages. I doubt there would be sufficient people who saw the hassle factor worth the benefit though. Failing that fisher with +8hrs stops mindlessly slow play but won't create an over the board type game.
