Nintendo has figured out multiplayer. They're still using Friend Codes, but you only need the one for your system. After you trade that, that's that. You are now able to play any 3DS game with them. As for actual multiplayer in games, I've played Mario Kart 7 and Kid Icarus: Uprising online and they are as smooth as butter. Seriously, I haven't even encountered slowdown at all.
It's easy to have no lag when there are no other players.
