These 'book' demos are based on the book "Advanced CORBA Programming
with C++" by Steve Vinoski and Michi Henning (ISBN: 0-201-37927-9).
This is widely considered the bible of CORBA programming and it is from
this book that the chapter demos are taken directly.  This book goes
into great detail on the subjects discussed such as the issues you
mention above.  As you are a newbie to CORBA, I strongly recommend that
you purchase a copy of this book.  It will explain any questions you
have much more lucid and succinct manner than I could here in a
relatively short email.  And as a bonus, the material covered in chapter
21 of this book will have direct correspondance to the demo you are
examining. 

Cheers.
