Hey David, could you show an example of this kind of script where "1 letter can be represented differently not only at beginning-middle-end but also also in relation to other letters"? This also ties in to the way I understand the Voynich script, so I'd be very interested to see what you mean.
Edit: by the way, I remember Diane wrote about papal correspondence on her blog, did you check there already?
