I sent you my current sketches the other day; I hope they help.  Feel  
free to ask me what I'm intending in them, or else what design  
alternative you favor.

Let's use the follow public page as a notebook on the project:
   http://wikis.sun.com/display/mlvm/InterfaceInjection

This page also has information about how interfaces work:

Basic idea is that each klass structure already includes (allocated  
inline) a 2-dimensional ragged table of its statically defined  
interfaces.  In meth.patch I've rationalized this a little to prepare  
for your work.  I put more extensive notes on the wiki page mentioned  
above.

Best wishes,
