one gconf daemon shared by multiple users

I have an unusual problem.  I wish to construct a system where there are
several applications on my desktop which are of different UID/GID's than
the desktop "owner."  For example, I (UID 1000) will have a
gnome-session, but will run firefox, evolution, and evince as UID's
2000, 3000, 4000.  The other UID's are not actual users, but accounts I
create just for these applications.  As such, I want them all to share
the gconf-daemon running from my gnome-session.  

How best can I accomplish this?  Is this a configuration/modification to
gconf or orbit?  Any help appreciated.  Thanks.
