Metastream already does this and it has to manually support a few hundred sites and the experience is truly awful. There are some sites where you have to manually enable autoplay but you know what? Most people will forget to do that. So now your little movie night is a major tech support waste of time. The need to constantly ask "are you synced?" Gets old pretty fast. Screen sharing is the way to go in my opinion but most capture programs capture the audio of the entire desktop. I have already created my own solutions for these problems.
