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.
