Plus on the 3DS, the main problem of the DS/Wii was already fixed: different friend codes across different games. On the 3DS, both players exchange friend codes, add them to the friends list and there. Whatever name that friend has, becomes the display name..across any game.For example, Super Street Fighter IV, you just go online and if another friend is already playing online you'll see his/her name and you create a lobby to play or join theirs.
Problem was that if the friend's playing offline you can't see him/invite him at all.
Mario Kart also solves this (apparently) by letting you invite people to join your game. The extent of that (only people online, only people playing Mario Kart); not sure.
So far, my only "thing" is still the lack of communication; so I usually ended playing 'Super' with MSN close and we both exchanging "lols" and "OMG" during matches.
