<i>its definitely scalable. Could you explain to me why it isn&#x27;t?</i><p>Imagine a world in which every ISP in the country had this system.  Let&#x27;s say that number is 1000 ISPs (with a typical 80&#x2F;20 distribution).<p>As a video streaming start up, that&#x27;s 200 ISPs that would need to be contacted and technical measures put in to place.  It&#x27;s likely that at least some of them are going to have incompatible requirements.  So now the bar for a new (possibly better) video service is not just maintaining browser compatibility, but also signing contracts and meeting technical limitations for 10-200 ISPs.<p>Sure it works for exactly one company, but it doesn&#x27;t work if the system is expanded to everyone.  In other words, it&#x27;s not scalable.
