Essentially, yes. I just don't think bittorrent makes sense for
anything else, because the git protocol is so much more efficient for
tiny incremental updates...
So the only other part of my idea is that we could construct a special
set of instructions that would allow them to recreate the carefully
repacked snapshot of Linus's repository without having to download it
from a central seed site. Instead, they could download a small set of
instructions, and use that in combination with the objects already in
their repository, to create a bit-identical version of the carefully
repacked Linus repository. It's basically rip-off of jigdo, but
applied to git repositories instead of Debian .iso files.
