It couldn't have been better timed. Amazon has announced their forthcoming CDN service on the AWS Blog. Once released this service will be a perfect complement to Panda, allowing videos to be streamed to users even more efficiently!
You will start by storing your content in an Amazon S3 bucket and then marking the content as publicly readable. Next you'll make a single API call to register the bucket. The call will return a domain name that you'll use to refer to your content in your web page or application. When clients request the object via the returned domain name they'll be routed to the nearest edge location, for high performance delivery.
