I think there is a big difference between distributing the root zone and distributing a few 'local' zones. In the first case you need something that is massively scalable. In the second case, just create a tar file with a zone file and a hash, put it up on a web server and the problem is solved. Verifying the contents of a file is not exactly a new problem. I wonder if there still is a use case for distributing the root zone. With QNAME minimization and NXDOMAIN based on NSEC records, the major use cases seem to be gone. Compared to other zones, the root is massively over provisioned. So if (from an availability point of view) there is need to have a local copy of the root, then you would need a local copy of .com as well. Though I'm sure that are people who want to reinvent DNSSEC. One final remark, maybe it is worth investigating a 'NSDEL' record type, and possibly 'ADEL' and 'AAAADEL'. Which are the equivalents of NS, A, AAAA for delegations/glue. With separate record types, we can define that they are covered by a RRSIG.
