The percent of requests is significant, but OpenDNS and Google and the other significant open resolvers are, themselves, anycast, so the geographic correlation is preserved.  Also, there?s an RFC for passing an origin IP tag along to the authoritative server, but I don?t know if anyone?s actually doing anything with that on any global inter-provider scale.
