Maybe. You can still use Kerberos internally, and so the cell could be 
in a realm. But with K5 you now have cross realm as a feature, and needs to be
addressed. This then this brings up the authorization questions.

AFS has done the authorization via the PTS. Will this continue to
work the same way? Would you map foreign users to local users in the PTS?
Will foreign users be allowed on ACLs? 
Do you still have the AFS ID? Do these need to be UUIDs?

How will AFS be different from DFS in these areas?
