Well, I've been wanting this (I mentioned it to you in SF in passing) for a 
while.  But I don't know the sizing code well enough to be able to write it up 
quickly.  I'm just not terribly comfortable yet with the overall internal 
design of mpl.  If nobody else does it I probably will, because I need it. 
But it will likely be _weeks_ before I even have a look.
