Features added in the current version of Kerberos Version5 are designed to allow inter-network authentication (in Kerberos terminology, referred to as "cross-realm" authentication). Recent proposals have included using public-key cryptography for both initial authentication of clients (TGT) and for cross-realm authentication. Such changes will make it more feasible for Kerberos to scale to larger sets of networks, but the question is far from resolved.
