People people, there really is no need to complicate things here. I'm an avid fighting game and online gamer. This is by far one of the best solutions out there. The best way to get people to stop unsportsman behaviour is to expose such behaviour in public. Letting others know that a person disconnects a certain percentage of times is not only exposing the DCer's online practices, but it is also truthful and fair for others who do want to play a fair match as they can then choose not to fight the DCer. You reap what you sow, simple as that.
There is nothing more frustrating than working hard to be on the winning side of a game only to have the other guy DC at the last moment. If you can't take a loss, DON'T PLAY THE FRIKIN' GAME ONLINE! Losing is part of the game experience.
