I guess I am conflating the design goal[1] with Sugar-as-implemented-now. I was talking about the design goal: that the Sugar HIG (through bitfrost) says Activities modifying other Activities' data is a priviledged operation not available to Activities by default[2].

I would be surprised to learn that the journal only interacts with the shell in those two examples that I mentioned. > As for the Zoom metaphor issue, the Journal inherits from Activity > like any other Activity. Can you point me to the journal code you're talking about? It looks to me like it doesn't: http://git.sugarlabs.org/sugar/mainline/blobs/master/src/jarabe/journal/journalactivity.py#line110 > Replacing the Journal Activity with an alternate Activity should be > doable. I don't think I'm arguing with "doable". I'm saying it's pretty far from the user experience the HIG talks about, for the reasons I mentioned (security, collaboration, shell integration). > James Simmons Martin 1. http://wiki.sugarlabs.org/go/Human_Interface_Guidelines/Security 2. http://wiki.laptop.org/go/OLPC_Bitfrost#P_DOCUMENT:_file_store_service "Programs on the XO may not use the open() call to arbitrarily open user documents in the system, nor can they introspect the list of available documents, e.g. through listing directory contents.
