 Yes, gnp is gnotepad. I was able to test gnp and old gnome - and yes, gnp
also wasn't loaded when session with it was started.

 Thanks for an explanation - the scheme you described sounds like exactly
what's needed. I hope it won't be too hard to fix gsm.

 We can hack script that starts gnome-session to start 'gdialog' (kinda
'xmessage' program for GUI interaction from shell scripts) popping a GtkCList
of saved sessions (if there are more than one session stored), and use the
user choice as ARG in gnome-session --choose-session=ARG. That's only 10 lines
of shell code, that will bring us that flexibility, without the need for
hacking any desktop manager. What do you think about this?

 Good luck fixing all this :)
