I haven't had too much call for such functionality yet, but it seems
to me it would be a useful tool for the OS to be able to send messages
to a running image. For example when a user double clicks an icon,
follows a link in a (gasp) non scamper browser and squeak acts as a
helper application (here is where my interest lies), or executes
something from a command line.
    It would probably have to be platform specific, and might require a
helper app, perhaps based on the VM, that just runs long enough to get
the info over to squeak or start it up if it's not running (I think
that's how emacs does it). I'm also not sure how it would handle
multiple images already running.
    Having written this, I'm sure someone will now point out that it is
already easily achieved, but I have not spotted the solution it my,
admittedly cursory, search.
    Any ideas or suggestions how to achieve this?

        Extensionally,
        Daniel Abeshouse
