This is like the best homebrew application thougt of. Basically it allows users from the wii friend list to join up as players, so what happens is that you run the application and then someone from your friends list join on your system so you can have 2-players connect as if they were on 1 system, obviously this would have to be through wi-fi/ethernet, but basically you have 2-player join up through the internet, so that you can play such games like wii sports over the internet.
