Hi Mark,

> I think we need a formal, multi-scoped anycast address space.

> Anycast also has enough properties in common with multicast that I think it should be more than just a configured special case address within the unicast address space. I think it should be a distinct class in between unicast and multicast.

I agree. Explicit is better than implicit.
