The zone transfer operation was designed for just such a purpose. It allows
one to snarf a piece of the DNS tree from a server. It is possible (although
resource intensive) to have a single site snarf ALL the 987 mappings from
the entire DNS system. Once this data was in hand, the mapping table could
be built. If this site was the one responsible for the worldwide tables, 
I think table/DNS coordination would be minimized.

ps. obviously, such a resource intensive operation would run infrequently.
