Is streaming from the web possible for Rift?

If you just asking is it possible, then yes. I think the technology is there. With Google adding Oculus rift support to the Chrome browser, I think someday content will be streamed to you. I think with technology like Onlive.com that streams games in real time over the internet someday it would be able do it. Doing what Onlive.com does to allow people to play FPS games in real time and not have the computer power in your house, could help with the Oculus Rift. Right now it is about balance of a good graphics card, good coding, and a good oculus rift to perfect frame rate for HD video.

If the computing power, and graphics card where in a data center somewhere in the US, and you only needed the oculus rift or other VR unit for display, then it wouldn't be so important for the customer or player having a high quality graphics card or computer system in your house. This would lower the cost of VR for everyone.
