[musictlk] Braille Codes for Neumes

[Sydney Walker Freedman]

Greetings!

     I recently read that a Braille system for Gregorian neumes was in the
works.  Does anyone know anything about this and when it will be
finished?  Also, is anything being worked on for Byzantine notation? 
I'm sorry about such an obscure question, but I'm a cantrix and an
early music major and would find these codes very helpful indeed. 
Thank you in advance for your help.
