An entire formula is easy: 

   \startbuffer 
   \startformula 
   .....  
   \stopformula 
   \stopbuffer

   \framed{\getbuffer}

For a partial thing you needs something along the lines of:

	\def\mframed#1{\relax\ifmmode
	   \vcenter{\hbox{\framed{$\ifinner 
				\else \displaystyle \fi #1$}}}%
	\else \framed{$\relax #1$}\fi}

Which allows \mframed{\alpha}, but with slightly less than optimal
spacing.

 WH> That reminds me -- has there been work on the math-part of

No, but I promise I'll get around to that in the next couple of
months. We first had to get some extensions to the font mechanism in
place, and that work is now finished.

Greetings, Taco
