Well, I'm not sure it make sense to explain it there, since DBus is
not involved in it anymore.
See the Exec field explanation on
When starting an activity instance Sugar is now just launching the
command line specified by the Exec activity.info field, adding
--activity-id and --object-id to it. This just work for activities
that supports multiple processes.
Activities that doesn't support multiple process will have to
implement some sort of IPC to ensure process uniqueness. The way this
is usually implemented in desktop application (firefox, evince, totem
* Instance1 starts, see that there are not previous instances running
and open Window1
* Instance2 starts, see that Instance1 is running and requests it to
* Instance2 exit
The idea is that in general activities should support multiple
processes. But for Web and Etoys we are going to special case Rainbow
to allow this.
