Since Mission Control is the D-Bus service for setting the user's
presence, I think the correct answer is (a).
As for the other options:
(b) This could also happen, but it means gnome-session either
make raw-DBus calls, or gains a dependency on tp-glib.
(c) This is what happens now. However, since you don't actually
have to run the Empathy roster to be connected to IM, or even be
chatting (remember Empathy is a set of processes that are a View
of Telepathy) it seems like the wrong place to me.
(d) Mission Control is meant to be reasonably platform
(e) A small program could exist to bridge the gnome-session and
Mission Control presences. It's about 15 lines of C or 10 lines
