Well I don't have a crystal ball, but I suspect we won't have a pressing need to back-translate PEF. In any case, it will always be possible to translate PEF to BRF and then back-translte that.

We will eeventually have the capability of producinng PEF. I'm wondering if we will be back-translating it or whether back-translation will be confined to ASCII braille. What do you think? I hope VewwPlus has an opinion. John B. -- John J.
