the equation editor included in Moodle through WIRIS math plugin is based on MathML. If you are editing a formula and press Control+Shift+X you will be able to edit the MathML code.
There is also a new integration with TinyMCE that will be usefull in Moodle 2.0.
Check WIRIS Tiny MCE integration and have a look at a demo.
