We don't use it locally and have simply assumed that instructors would prefer to author equations in more sophisticated tools and copy the MathML or LaTeX output into Samigo.  The second assumption we've made is that JavaScript is preferable over Flash in almost all cases.

LaTeX was here first, and often favoured by those working since and math  (that aren't also web devs) because of its ubiquity.  MathML has merit, LaTex is hard to dethrone.
