That's what Nominum's GNS service is.  It's hosting some cc-tlds and
whatnot at the moment, although they haven't started selling it to smaller
customers yet.  http://www.nominum.com/GNS/index.html  No details on the
site, but David Conrad or Paul Vixie or I can tell you more about it.
Basically it's a global network of redundant pairs of heterogenous
nameservers (Solaris on Netra UltraSparc and NetBSD on IBM Netfinity x86)
with IP Anycast so you always get the nearest pair.  For example:

Both of those traces are running through AboveNet, but locations are BGP
transit multi-homed and peer with a lot of providers, and since it's
stateless UDP transactions, all the fail-over is transparent anyway.
