We don't need this for 1.0 do we?

Anyway, beyond logout/shutdown/reboot request, we'd need:

(1) client registration/tracking, including the ability for the server
to notice immediately when a client exits, at least for some clients (so
we can restart the panel, file manager, etc, if they crash).

(2) logout notification/cancellation, which requires the SM to be able
to address individual clients (so it can tell them to interact one at a
time). So does that mean we need an interface for clients to implement,
in addition to the o.f.SM interface for the server?

(3) state saving. (Havoc will probably say we don't want this, but I
don't think there's a consensus around that, especially at the fdo
level). The way XSMP does this is really messy and doesn't integrate
completely cleanly with autostart, so ideally we'd do something better
than a straight dbusification of the XSMP API. I'm playing around with
this in new-gnome-session and will hopefully have some better ideas soon.
