At the time of publication of the article the tool used to create the minimalistic VM Tinyx was not released and as far as I can see was never released.
Correct, we never did release Tinyx, mostly because it was in a very unclean/researchy state = not ready for public consumption. In retrospect, we probably should have either (a) made it available in whatever state it was in or (b) put more cycles into it.
