I know Justin has played Mario Cart through Wi-Fi, but I'm not exactly sure how... I just asked him and he said each game is different and he doesn't know how Pokemon Pearl does it. Sorry I'm no help.

Playing over Wi-Fi you don't need to be near the people you are playing. You don't even need to know the people you are playing with. Some games are 2 player and the person you are playing with needs to be within a few feet of you and the have to have their own DS (they however don't need to own the game, they can 'share' yours)... playing over Wi-Fi is different.
