Actually that's a very good point that hadn't occured to me. I'm still at a
loss of any examples where knowledge of the document must be public
knowledge but the signer cannot be, except possibly to give anonymous
testimony to something, where the testimony could be verified later. Maybe
that's enough. I'm not sure it would seem to be a business end of things,
and I'm an engineering end. Does anyone have any examples? Or is this a
non-issue from the business end also. Or would simply forcing detached
signatures with out of band ordering information be enough?
