I'm also not a big fan fancy browser demos. People have this fair speciation that anything in a browser will run well on their 5 year old laptop. This is basically true. Except for when you get into 3d content. There's also an expectation that things load relatively quickly. Rich games with tens to hundreds of Meg's of content do not load quickly. Then they continue to not load quickly everytime you go back to that page. (If not everytime, then sometimes, which is even worse)
I do agree that there should be a fast and easy way to experience VR, uh, experiences without having to download native installers for every one. I'm not sure what way that will be. I am extremely unsold on the browser being the solution. But if it works out then that'd be pretty nice.
I think the browser will be powerful enough for some simple VR experiences that consumers will want to engage with for <5mins. At least at the beginning. I've been working with the webVR stuff and have gotten a consistent 75 fps on an MBP, which is the DK2 limit. Not a 5 year old laptop, but also not a heavy gaming rig that Oculus expects people to own.
Maybe webVR won't be the way to get AAA titles in VR, but it will certainly lower the barrier to 1) development of VR content 2) distribution. I think webVR can do a lot for the adoption of VR without "poisoning the VR well."
