Last time it was discussed I thought that the provisions already in the DNS RFC's to allow zone transfer for "." to recursive servers is a neat solution for the root zone.
There are pluses and minuses to that approach. The people at .biz and .info are _still_ getting complaints from people sitting behind broken resolvers with bogus copies of the root zone. Doing this in a widespread manner is likely to lead to more problems of this sort for new TLD's, and updates to existing ones. Also, if you consider that <some high percentage> of root server queries are for the same say, 10 TLD's, and that those records are cached for 2 days, it would most likely be a net increase in root server traffic to have millions of resolvers slaving the zone. Speaking only for myself, I think the combination of anycast and DNSSEC has the best chance of success; both for the root and gTLD servers. Doug
