Aside for "inline" framed boxes for math, it will be nice to support 
"display" framed boxes. For example, see the attached image from the 
empheq package for latex (I know Hans doesn't like to read big pdfs from 
latex packages, hence the attached image ;-)

If framed could be incorporated into formula, we could easily create many 
fancy boxes.
