In what format do you desire letter ballot comments?  Simple in text like 
we submit officially or some other way?
One of my reviewers was confused about the max packet size.  I assume that 
max packet size is the maximum size of a single packet but that a single 
SCSI data transfer may be composed of multiple packets.  Is there a limit 
on the maximum SCSI data transfer size (e.g., logical block size)?  I 
cannot find anyplace that defines that a SCSI Block may be transferred in 
multiple data packets.
I see no definition of a Data Information Unit.  I cannot figure out how 
we would indicate that we are sending data in the packet when there is no 
Data IU.
