In the design of GNOME 3

 Every window must belong to an application
 Every application must have a window, possibly hidden [*]

Since user isn't going to be able to manage the concept of two different
chat applications that handle half of the job, both empathy-chat and
empathy should appear as "Chat" to the user. I think you can do this by
after GTK+ is initialized by calling:

 gdk_set_program_class ("Empathy");

(Where "Empathy" matches empathy.desktop with an initial capital). 

Alternatively, you could on a window basis do:

 gtk_window_set_wmclass (window, "empathy-chat", "Empathy");

You need to do this for all toplevels, but don't need to do it for
dialogs with a parent. (If set_program_class works, I'd just do it that
way.)

When the Empathy desktop file is clicked, currently the Contact list
should appear as the best proxy for a "chat application" window. From
discussion at the summit, it seems like the long term direction here is
likely be to make the main Empathy window more of a "recent
conversations" window and less of a contact list. (GNOME will have it's
own all-sources contact-list in 3.2 or so.)

Another thing that I think is part of the overall picture is that
Empathy should be "sticky":

 - If you run Empathy and it isn't already autostarted, it should add
   itself to the GNOME autostart.

 - If you explicitly quit Empathy, either through the contact list
   window menu or through the application menu [**], it should remove
   itself from autostart.

The idea here is that being online isn't an activity that you "choose to
do" when you log in to the computer, it's a state. You shouldn't have to
think "I want to chat with someone" before someone can chat with you.
And you shouldn't have to find some obscure option to make it autostart.

[*] Hidden isn't really worked out yet, but I think the current Empathy
    behavior buddy list behavior in GNOME Shell where if you click the X
    on the window, it "minimizes", and you have to go to the Activities
    Overview or alt-Tab to get to it again is OK for the moment.
    Having clicking the X button sign you out of chat if and only if
    you have no chat windows open would be too weird.

 [**] Currently the quit menu in the application menu just closes all
      the windows, so isn't distinguishable as a "quit" action, but
      a working application is a must-have for 3.0.
