Final Fantasy III to make full use of stylus, Wi-Fi

Speaking to the ever-spectacular Japanese magazine Famitsu, Final Fantasy III executive producer Hiromichi Tanaka (who also worked on the original FFIII) discussed the changes made to the DS version. Of course, we have all seen the lush 3D visuals, but Tanaka explains that the game is actually played in "virtual" 3D – you can zoom in and marvel at the scenery, but you cannot rotate the camera (except in buildings – thanks, Babu).
For the characters, Tanaka has given them more of a personality integral to the story, as well as balanced the ever-popular jobs system in the game.

Tanaka's goal with the game, although he does not explain how he intends to accomplish this, is to allow the gamer to play through the game exclusively with the stylus. While battle mode seems fairly obvious, how are the menus and world movement going to work? Tanaka also plans on utilizing the DS' wireless abilities, but reveals only that it would be for outside the main quest. What multiplayer features would you want to see in the Final Fantasy III
remake?
