I believe the 3DS has stereoscopic video recording abilities, that can also be replayed and viewed in 3D. Here's my idea of a homebrew app: one-on-one 3D chat. The stereoscopic video data could be transmitted through a web socket between two users, who could watch each other in 3D. Another web socket would transmit between the mic and speakers of both users. I have made a socket chat homebrew app before, but with no video or sound options, so I believe I am up to the task if people are interested. Do you guys think something like this might be possible?
