Muchos Kudos to Sylvain who over some exchanged e-mail invited me to explain more about some of my previous rumblings on the cocoon flow... turned out to be quite some shared neurons experience...
After the mail exchanges I 've been rehashing the thoughts and writing them carefully down in a quite lengthy RT on the wiki. Hoping to make sense. If you can't spare the time over the lengthy read: you might get enough out of the great synopsis Sylvain posted.
Back to work, now. Doing some actual hacking on my woody-binding idea... hoping to be able to send in some code for peer review soon.
