DASH uses big chunks of operator selectable size though as it is codec agnostic. I wonder if coupling transport and codec could have benefits for the massively scalable VOD case. (ie pre-render a bunch of stuff up front and run a "lite" codec that is coupled to the transport layer and aware of network conditions)
