I find myself inadequate to keep pace with the effluence of the IP storage 
reflector, so please forgive me if I've missed some subtle point in 
Howard's proposal and John's reply (above).

If I understood, Howard was suggesting that the usage of LUNs be bypassed 
in favor of direct use of unique identifiers possessed by logical units. 
This DOES NOT affect CDB structure. The presence of a LUN in some CDBs is 
vestigial and may be ignored.

How to specify a LUN (and what it's maximum size may be) is a matter for 
the transport "container" that gets the CDB to the LU. This is entirely 
within the domain of iSCSI.
