So there is no need to anycast the DNS servers and rely on BGP topology for selection. Instead use bind's behaviour so that each resolving nameserver will be querying the authoritative nameserver that responds the fastest.
However, note that only BIND does this. djbdns always selects nameservers randomly and the Windows selection algorithm is somewhat of a mystery. See http://www.nanog.org/mtg-0310/wessels.html Duane W.
