Capturing WiFi trades in X/Y

[proGlockner]

Hi folks,

I'm new to this forum, but recently read into the developments of capturing Pokemon files from the newest Pokemon games. So I learned that the Wonder Trade was used to get unencrypted Pokemon data, but since Nintendo added an encryption of the connection with patch 1.2 one is reliant to hardware solutions like Powersaves.

Right now I'm asking myself the question, if it is possible to capture the Pokemon data which is transferred between two 3DS systems via WiFi trade. Do you guys know some further details on how the connection is established? Is it encrypted, too, or isn't it even possible that a device other than a DS is able to capture the WiFi signal between the two 3DS'? I didn't find anything regarding this on the forums... maybe my idea is just stupid I guess, but anyway, I'm curious
