Alright. Firstly, for ds games, that is game dependent, since networking features were hard coded into the game to work with the DS and DSL. The only way a 3DS could say allow the use of a WPA network for online features of a non dsi enhanced game would be to use some sort of wifi "wrapper" that MIGHT be able to use the connection your 3DS is already connected to. This would involve some tricks with the way DS mode communicates with the wifi hardware, since you would fool the sandboxes DS into thinking the connection the 3DS is connected to is a available hotspot. One of our forum members, Rydian, has agreed tht it MAY be possible, especially if someone like neimod has kernel access.
