Why not just create another side project that's web based and includes this
"sandbox" idea? An app designed from the ground up for viewing this crap.

That way the browser itself could remain committed to it's principles and
anyone that wants to can use the non-free junk can do so without affecting

I agree with Chris that we need to have at least one major browser without
this nonsense. That way websites will feel pressure not to put ALL of their
video (DRM or not) into this rat hole.
