AS112 was the grand experiment for unowned anycast, and we all felt
generally safe experimenting with the live network in this way at that
time since answers to 10.IN-ADDR.ARPA did not have to be particularly
reliable. what AS112 proved to my satisfaction is that debugging was
neither concerning nor discouraging.

that's why xiaodong, zhiwei, and i are proposing unowned anycast for the
root zone in

http://tools.ietf.org/html/draft-lee-dnsop-scalingroot-00

which is exactly the "multiple operator on a single anycast IP address
approach".
