I'm sure someone will correct me if I am mistaken, but I believe that
the difference between the master backend and a slave backend is
that the SQL database resides only on the master.  I'm sure there
may be other differences as well.  I am only running 1 box with both
backend and frontend so I am not speaking from experience.


P. S.  Stan.  Buddy.  Pal.  Please, please, please, please take some
typing lessons or run your emails through a spell checker before
sending.  They are painful to read    ;-)
