Someone over on the python-inside-maya group just posted a script for something similar, it generates joints aligned to poly edges, then rolls/folds them up in strips.
Also found this reference on the SOuP forums, but the general vibe seems to be 'doing it by hand is easiest'.
I worked on an amaaaazing origami ad at the mill many years ago, the rigging and anim team just brute forced their way through some of the trickier transitions. One of the nicest things I ever worked on, then the client hated it and it never aired. :/
