I'd venture to guess from the presentation and the site that this is basically trying to be Node.js with a graphics engine attached. ie. Throw away the browser DOM and provide a bunch of new apis (and maybe a few existing ones which already seem ok, like the canvas stuff). I'm curious what you get as a benefit of doing this instead of just using Node itself and providing an api to work with the graphics/sound/whatever engine. No HTML or CSS renderering -> A considerably more plausible project, and certainly one that won't complete with existing browsers in the short term.
