AFAIK at the moment all activity installation is manual.

At the moment, the shell is required AFAIK.

You can *almost* get an application to work just by specifying an exec.
The application will start (I just tried this with the Inkscape SVG
illustrator running on an emulated developer system, it should work the
same on a real laptop), but Sugar uses a number of dbus messages to
track the state of each activity. Because your C application won't
respond to those messages Sugar will "lose track" of the application and
won't know to hide the frame or show the application in its activities
view or otherwise continue to manage it once it is started.
We'll likely want to fix that so that Sugar doesn't *rely* on the dbus
responses to track the applications. That should be a straightforward
