Is this really neccessary? Preview-LaTeX takes for example "\emph{bla bla 
bla}" and passes it to an external tool, latex, which creates an image that 
replaces the corresponding text. Wouldn't it be possible to let the user 
specify another tool (probably a simple lisp function) instead that takes 
"\emph{bla bla bla}", processes it and creates soem text (eg. "*bla bla 
bla*", faces might be problematic) that is used to replace "\emph{bla bla 
bla}"?
