Speaking of that, how will ownership be handled in HAMMER?

On NFS, last I checked, the user and group IDs are assigned to the
files on the server machine, but anyone on a client with the correct 
user ID has access to the file.  This means root on any client can
modify any file on the server.  So all clients need to be trusted.
Is there a way around that in HAMMER?  

Also, what authentication mechanism would be used across nodes in a
cluster: NIS, LDAP, or something else?
