The latter. But it is not really evil ;-). It serves our purpose admirably. 
LatexMorph Etoy is a tool that uses OSProcess to invoke latex on the 
underlying host to typeset LaTeX commands but the resulting graphic is cached 
in the Etoy. On hosts without LaTeX, the graphic can be seen but not edited.

Of course, a project with this Etoy will not load into an image without 
LatexMorph. The Etoy itself can be trashed after the graphic is extracted into 
an ImageMorph if its use outside of our schools is intended.

The code is available in http://www.squeaksource.com/LatexMorph. It needs 
OSProcess (in the image) and latex and dvipng on the host. See LatexMorph 
class for examples of usage.

How is OSProcess more dangerous than console shell access?
