Streaming is totally fine, but I'd request to @doublevr that the Deo WebVR be activated in 4K. I'm fairly new to VR and have a very poor system. It would be fantastic if you enabled the 4K streaming option as an alternative for low-end users, like myself, interested in the JAV. As I understand it, downloading the JAV is out of the question because of your contract restrictions. But downloading streams of it should be fine, or at least it is for my friends who subscribe to the source R18. Right now it's only possible to use the SLR implementation of Deo WebVR for 1980 x 1980, whereas the Deo site has an implementation of the web format that allows for true 4K and even higher. Lots of foreign users with slow connections and bad rigs, like me, would benefit from the minor improvements in image quality. Amazing site, though, with fast servers and great content!
EDIT: Maybe I'm getting it wrong, because I recall reading on here that it is possible to stream at 4K in the web interface; but the implementation of Deo WebVR on this site shows no option for 2160p, which is the most common standard of '4K'.
