Stereo Web Tests - Update
It works! It's not perfect but if you have a 3DTV and an internet connection, you can stream stereo from the web. I tested both in Vimeo and in YouTube and Vimeo actually works much better (big surprise). When you go from Web to 3DTV, something weird happens with the convergence plane creating more parallax then is intended. Vimeo more so than YouTube. I'm looking into why this happens and what some potential workarounds might be. In the case of Vimeo, all you have to do is "bake" a 1080 Side by Side video and upload it. The picture quality is what you'd expect from Vimeo, acceptable but not perfect. Really the best delivery method for consumers is still BluRay or even better, 4K projection.
On the LGTV's remote, there's simply a "3D" button which will take any picture that's being displayed and attempt to put it into stereo. If it's a correctly mapped Side by Side image - coming from a Blu Ray, web, or whatever; you're good to go.
