This sounds a lot more like IP multi-casting and/or the MBONE, which _has_ been applied to live audio/video transmission. I don't know of applications of IP multi-casting to file-serving. Doing much better with IP multi-casting than multi-level proxy caches might require advance knowledge of who would want what files where.
