"Full transit to everybody" was a good idea to get a pretty tightly 
meshed IPv6 network into place, which is *good* because it means that
you have (typically) only few AS hops to traverse - and thus fewer 
networks in between that can mess up your routing.

Won't help against Ghosts, of course, but there is nothing besides
establishment of a clear upstream/downstream structure and strong
filtering on the downstream BGP sessions to fix *that*.
