I told you they have an algorithm that combines the Mii's code with the game's code (with the Wii's code...) to create a unique code for the Mii/game/Wii combo, so that you can only play online with that profile/friends list with the same copy of the game on the same Wii system. It is, so far, the exact same system as the DS, only you can have multiple friends lists on the same system. But if you say put in a different copy of the game, it won't work, it'll give you a new friend code even if you use the same Mii and system. Or if you transfer your Mii over and put the game in a new system, it'll give you a different code. Try it out.

Doesn't mean it'll always be this way, especially for third-party games which have a little more flexibility (EA is doing something similar but different with their games and EA accounts).
