I can confirm that IOS (and assuming NX-OS) supports Anycast RP using PIMv6 (RFC 4610). However, I haven't tested this for Embedded RP so not sure if that throws a curve ball. The challenge with Embedded RP is it become a new application requirement. From the network perspective it's not a big deal. However, from the application owner perspective it could be. I can't speak to that because I'm not a developer. It is a change from IPv4 though which means it needs to be sold to the App-Dev group.
