I don't have a Go yet, only Rift, but I do have a Mirage VR180 camera. For me, using a Go to allow me to watch photos and videos together with someone else using the Rift and the Go simultaneously would be the killer use case for the Go.
From googling around the only thing I found that sounds like it might do what I want is something called vr-sync but it appears to be prohibitively expensive for casual use.
Does anyone have any experience with these kinds of software? Is there anything usable and affordable out yet?
And since I want to preserve the quality as much as possible, I don't think that anything that involves uploading to facebook or youtube or a PC desktop sharing app would cut it.
