Hello,

The problem with MathML is that it does not seem to have been designed with 
editability in mind (in spite of what their website says). However, since 
their approach for displaying formulas is the same as that of KFormula, I 
think it would be feasible to have a common code base.

Note that KFormula works with DOM anyway. As a rule, I don't expect everything 
to work the first time. We can (should?) do it a little at a time. I don't 
understand the KHTML code well either. For a start you can look at the 
following thread, where they discuss where one would have to start to bring 
MathML to KHTML:
  http://lists.kde.org/?l=kfm-devel&m=101822942829091&w=2
I would be willing to work on it. But I don't think I can do it all by myself, 
as I have no experience with displaying formulae. We could set up a meeting 
on IRC if you would like to figure out a plan of action.

Regards,
Ravi
