Thanks for the info.  Here is what I am suggesting for future version of gnome 
(I hope Gnome developers are reading this).

All we need is like you said, a C-wrapper program that register with the 
session, or a gnome program that when called from the script, registers it.  In 
other words, Gnome should provide such generic C-wrapper/registering program.

I do not know much about Gnome programing and even less with registrating with 
gnome-session, else I would provide such at tool.  But if there is any Gnome 
developper which has an hour to create such a tool and have it included with the 
next Gnome release, that would be nice.  Might be usefull for more than one 
person.  Somehow I feel that we should make it easy for people to run scripts 
from a gnome session.

As for myself, I will try out the .xsession solution for my needs.
