Really, there's no "hopefully" about it.  The place name contains few enough 
values and is short enough to fit in a value label.  The revised dataset 
will only add about 3 bytes per observation (an int and a byte), so it will 
only require about 60MB of RAM which will easily fit within the 666MB 
remaining.
