This is actually addressable lots of different ways, all relatively reasonable: i) an arms-length company holding the coordinating database (CDB) ii) a closely-held domain with the ``owner'' holding the CDB and franchising to registries iii) several registries acting in a consortium, with registry ``a'' holding CDB A, b holding B, ... f holding F and all registries being able to register domains in A through F iv) a company specializing in high-reliability systems holding CDBs for others, with hot-filover to different machines and sites (the ``weak distributed database'' case: they do have to do a rollforward to get up the the state where a new server can take over, but it takes only minutes). | Maintaining a shared TLD is a pretty straightforward database problem | if there's a central registry, and a fascinating research problem in | distributed shared updates if there isn't. I'd prefer to leave the | research problems for the researchers. and (v), a company who claims to have the realtime distributed databse problem solved, selling it's technology to the registires as a showcase (;-)) - --dave - -- David Collier-Brown, | Always do right.
