Mirrors are stacked in a tree (and even graph for some that use
fallbacks) and pushes travel along the mirror network down this
tree. The Mirrors.masterlist (apt-get source base-config) file
contains a line where a mirror updates from.

cdimage.d.o uses bt now for its images.
But BT has limitations. Esspecialy with the number of files to
share. A tracker that coordinates a full debian mirror would have to
be insanely huge. Also P2P tend to ignore the geography of the
network. It is much better to download debs from one local mirror than
connect all over the world to countless users.
One thing that might be intresting though is replacing mirrors with
smart caches. Act like a proxy with prefetching for commonly used
packages.
