The basic idea is to export in vector-PDF file, the math equations that you have develop with any program (i.e. MSOffice, or OpenOffice(which I prefer)). Then you can raster the equation in high resolution through photoshop (from the vector-PDF file), and trace it to perfect outlines via illustrator.
Btw. OpenOffice Math tool, is an open source tool, that Adobe can utilize thus to make automatical this procedure in it's next suite. Simple and easy without having to mess with complicated implementations... :)
