Less and less would be my estimate. How much video is cached ? How much P2P is cached ?
If you asked Akamai, Limelight and friends, they might tell you that 100% of important video is cached. And viewed from some angles, every peer who receives a block of data and offers to serve it to others is caching that block of data for the benefit of other peers.
