Re: DAISY reader et al




Probably way out of my depth here (nothing new in that), but I would
imagine that if someone is going to go to the lengths of making you
sign a NDA to gain access to the specs that this would also preclude
providing source because anyone who has the sources would be able to
determine the specs fairly easily without having to sign the NDA. 

Probably the only way we could provide the sources and not get into
strife for breaking a NDA is if someone just reverse engineered the
software without having signed any NDA with Daisy. However, if its is
as ugly and complex specification as Raman indicates, then this would
be a non-trivial task. 

The only other alternative I can think of is if someone is prepared to
sign the NDA, write the software as a stand alone application and
distribute it in binary form. Then it should be trivial to create an
emacs/emacspeak interface to it which would not infringe on the GPL
nature of emacspeak or emacs.
