It will be interesting to see how much of the &quot;stack&quot; ends up being open and royalty free.  Don&#x27;t get me wrong, open format is great, but only part of the story.<p>That being said, I&#x27;m definitely optimistic this is a step in the right direction given the fact that Mozilla is a part of it.<p>EDIT:  Actually, looks like they may be proposing full-stack will be open:  <a href="http:&#x2F;&#x2F;aomedia.org&#x2F;about-us&#x2F;" rel="nofollow">http:&#x2F;&#x2F;aomedia.org&#x2F;about-us&#x2F;</a>
