How about this as something *way* simpler? Define a way of marking the top of a particular directory hierarchy as a tree. Then the *only* way of updating that tree is all or nothing. That is, someone submits a signed tarball; then after the signed tarball has its signature checked, it gets unpacked into a dir.new, and then we rename dir to dir.old, rename dir.new to dir, and then dir.old gets removed. That way there's no conflicts between directories that are managed via the kup-servers PUT and DELETE commands, and those where they get uploaded as a single tarball to create or replace a specific directory hierarcy, or which can be deleted only as a entire directory hierarcy.
