I think this would be a valuable improvement, though, if you could feed changes
through some mechanism and then do the image build on the mirror server, you
would save everyone a ton of effort and bandwidth, and the CPU time is minimal
to do the image build.
Using a bittorrent approach can't actually be too hard to do if you wanted to do
it, I bet most mirror sites could nfs export storage to save the bytes, so you
just need any small system running Fedora and a few scripts to pull the images
down and seed them. Note: I said "not too hard" rather than trivial, because
error correction is needed. I still think a jigdo style delta+build solution is
best, if overall bandwidth is to be saved.
