(I tried this first at http://math.stackexchange.com/questions/187265/mathjax-or-something-like-it-as-a-classroom-blackboard , but didn't get satisfactory responses.)
What is the best desktop application available now for running MathJax (or the equivalent) in the classroom?
I can't depend on having a connection to the web, so I'm seeking a stand-alone application. To be clear, I'd like to type as I talk and have the students see the typeset mathematics with as small a delay as possible. At the end of my lecture I'd like to be able to export the notes in some reasonable elegant way.
Just today I experimented with Qute ( http://www.inkcode.net/qute ) - and found it barely adequate, though the lack of adjustable font sizes would make it illegible beyond the first few rows.
