Further note to this.  
a) All the commercial and non-commercial ILS systems used by more than one institution of which I am aware either added MARC processing or died.  
b) All of the systems for which I have seen the underpinnings have mapped the important values from the Marc record into various other SQL data structures.  They may store the Marc on the side or  assemble it on the fly at the point of demand.  Marc enters and exits the system but may or may not drive the internals.
