I'm often asked: When will MathTran support LaTeX?  The problem is that 
because MathTran uses a secure variant of the plain TeX format (so we 
can run TeX as a daemon), and so commands such as \def are stored in 
inaccessible locations such as \_def.

Is it possible that this project could be done in a way that produced 
something that would help MathTran support LaTeX?  As I recall, it took 
me about a week to create a secure variant of plain TeX.  I'd be really 
interested in a similar port of AMS math.
