Tar must do some processing of its source contents then?  The original 
suggestion for using dd in this thread came from Niles Rogoff, and his 
prescription was to use usplit.  I don't know that this command is 
native to Ubuntu, but I believe split is.  And if split merely does 
that, then it seems like ntfs or unix permissions should be preserved.  
Agree?

And I think I still have this question lingering: Does dd knows how to 
prompt for the next DVD (the next split) during a restore operation?
