MathML has many problems, this is also why it isn't KFormula's native 
format.
However, a common code base in kdelibs makes sense.

I'm not much experienced with displaying formulae either. It was my 
brother (Ulrich) who wrote that code (who also had to study TeX & Co 
first). But the rendering could be taken in most parts from KFormula 
(these parts should of course be put in a seperate lib -- the common 
code base discussed above). However, as it is put out in this thread you 
refer, every addition of this kind however makes KHTML bigger and slower...

A meeting on IRC with you, Uli, me and everyone interested is quite a 
good idea(tm).
