A) ProDOS doesn't have any format code which can lay down these headers,
   so there is nothing to modify except the access routines.  You would
   have to write your own formatter, and then write a ProDOS directory to
   the 'different' disk.  This would involve writing a program which
   could access both formats at the same time during copying, which
   wasn't really too hard.
B) If you are protecting a product, then you should check to see if Apple
   will allow you to distribute a modified ProDOS with your copy
   protected software.  I don't think so.  The Disk ][ driver will
   probably not behave or stay in the same locations.
C) If you are working on a product, then you could probably use some good
   documentation: buy Beneath Apple ProDOS.
D) If you are NOT working on a product, then why would you want to cause
   yourself such trouble?  You can just go out and buy some copy
   protected software if you really want that kind of headache. :-)
