Is possible stream your 3ds game while you playing to a computer with Wi-Fi connection or with other metod?

You need a modded 3ds and a Capture Card. Its the only way (costs money)

I don't think the 3DS wifi is fast enough. And it's probably not possible on o3DS because video capture would take too much CPU/GPU power.
But it might be possible on the n3DS thanks to the extra CPU power, with low bitrate so that the wifi won't bottleneck FPS.
If such a feature is made I would expect to see it in NTR-CFW first.
