Keith Kocho is the founder of Extend Media, a company that manages online video assets for content owners.  Its closest competitor is the thePlatform, now owned by Comcast.

The company is powering the backend of Fanfare, the new video and music Web download platform from SanDisk — which is producing the Sansa, a cool device that allows video files to be saved to a portable memory device.  Steven Miller covers it in tomorrow’s New York Times.  Here’s Walt Mossberg’s review.

Keith was in the Beet.TV studios earlier this week.  He told me about the Sansa project.  We’ll get to that shortly.

But, here’s his take on how cable companies are beginning to "throttle" or limiting  the amount of P2P traffic they allow through their pipes.  There’s been quite a lot of discussion about throttling recently by Comcast.   

Keith expects that this issue of bandwidth will have a significant impact on Joost.
