Awesome project.

Despite the flaws, the nice thing with VNC is its universality to support any apps on a computer. Using HTML5 in a browser limits the scope of things we could encapsulate as environments, and makes it less "universe".

However, there is a difference between the universality of the tech stack and the exposed interface. In my opinion, the future universe would be rich clusters of RL environments with unified API, each of which implemented using different underlying technology to meet the desired synchronicity and frame performance.

HTML5 could deliver one of such clusters.
