It appears to be implemented. When I ping the subnet anycast from a Linux or Windows XP box I get a reply from the IPv6 router on my LAN. The router is a Linux box running Kernel 2.6.31. Interestingly, on a Linux box, the ping6 command shows the router's unicast address answering the pings (same goes for ping6 under Cygwin on a Windows box). But on a Windows box ping shows the anycast address answering. However, in both cases packet captures show it actually is the unicast address of the router answering, which I believe is the expected behavior. Windows ping just shows the wrong address for whatever reason.
