Yeah, maybe.  I think the bus name is more important than the process
name.  Currently we have:

   org.gnome.evolution.dataserver.AddressBook1
   org.gnome.evolution.dataserver.Calendar1

perhaps the new service would be named:

   org.gnome.evolution.dataserver.Sources0

Reconnect?  The usage pattern I envision for proxy object is to connect,
obtain all the sources somehow (details TBD), and then just listen for
the occasional add/remove/change signal.  If the proxy has to reconnect
and refresh its set of sources, it's trivial to filter out by UID the
sources it already knows about.

Point is, all the details should be hidden in the proxy object.  Should
be transparent to clients.

I think David added the code generation shortly after you wrote all that
out by hand.  I remember thinking of the irony when that landed.

We could look into using the code generation tools for 3.4 if you think
it's worth it.  Since it's in GLib now I don't think we'll get stuck in
the "generate once and it rots forever" trap like last time.
