After we branch for the new feature development for gnome 2.4 :)  Though I'm
a bit worried about the scripting and "evil" (trojan horse) themes.  Though
the commands are run as the gdm user, still that user could get quite a few
things done (such as steal cookies and stuff).  Perhaps what we need is to
run the scripts as nobody, though I'm not sure how we would do that from the
greeter.

My current thought is to have "AllowExecutablesInThemes=false" be a default
and for the gui config to go through the selected theme and warn the user
if there is an executable in it (and optionally it could list the exec
lines).

My current thoughts on this is to just write a special session for
that particular setup, then this script could check the groups of users
in whatever way the sysadmin wants and run the appropriate session script for
them.  Similarly you can add code to the session scripts to disallow certain
users from running certain sessions.

I don't think I would take patches to the session setup since hopefully
someone is going to write a common session setup spec on the xdg list (you
can always volunteer for that:) and then I want to implement that.
