Hmmm - looking at the docs for multi_array (which I had forgotten about) 
makes me think this is the solution you should look into first.  It's 
dated 2006 and/but has the imprimatur of some of our best developers. 
It's a little hard to understand from the docs.  Perhaps it would be a 
worthwhile investment to use some modern TMP to improve somewhat the 
interface/API and of course sync up the docs accordingly.  Sounds to me 
like a small yet very worthwhile and interesting project.
