This sounds like fun, especially if webpages can use WebGL to read old buffers back into javascript variables - and then AJAX them out silently in the background. (preserveDrawingBuffer + canvas.toDataURL() + ajax ?)
Edit: Also, "google chrome incognito mode is apparently not designed to protect you against other users on the same computer".. what? Isn't that the only thing it can and should protect against? It's not like it can protect against non-local users (i.e. HTTP network interceptions)
