It would be possible to create a browser that displays DRM content and ignores DRM. The only thing that content publishers could do is ban that browser. And then it would adapt to disguise itself as other browsers.
DRM on the web can only happen if all of the major players (that is, browser publishers) agree to play along.
I am very excited about this news, this is probably the most important news in weeks, and could impact the Internet for years to come.
