Simplistically, it cuts a line between rsync and bittorrent. Downloads blobs by hash, and then hardlinks them into the tree. Mirrors would then get swarming behavior (there would still be tiers; the first-class mirrors would be seeded first then "manifests"[1] would be released to public mirrors). Only once a mirror has a complete update would it publish the new packages in the public tree. We talked at FUDCon Toronto with warthog9, Matt Domsch, and Seth Vidal and they liked it. Unfortunately, not much time has been spent on the project much from either of us of late. - --Ben [1]These are be GPG-signed and verified lists of every directory, symlink, and blob in the tree.
