In fact, caching represents one type of innovative network practice encouraged by the open Internet.
Perhaps because Mr. Whitt is a corporate executive rather than an engineer, he is not aware that YouTube videos are in fact not cacheable by design. As mentioned at http://wiki.squid-cache.org/ConfigExamples/DynamicContent/YouTube
This is a VERY soluble problem, if it's even a truly significant problem. And with the right pressure by operators, YouTube engineers, some of whom I know and know to be quite smart, would be more than capable in solving.
