Well yes, especially since brltty already has all the foundations
laid of serial, usb, usbserial, and working with many displays and
notetakers, and not just as a terminal either.
I don't think it's a given that what's needed to read the screen is
available just because vo does it; vo is done by Apple, not a third
party. And I'm not at at all sure vo reads all that could be read;
didn't somebody mention proloquo (not sure I spelled right) seeing
some things that vo didn't? Furthermore, my experiences in linux
using braille and speech found braille to be much faster so that
speech was still chattering away and had to be silenced when braille
had the information already done; this was especially true when
combining brltty with speakup. Brltty does have some speech built in;
you can control whether it's off, whether it's on autosay, or whether
it only speaks the output when you press the appropriate keys on the
display or notetaker; also allows for cepstral voices, dectalk, and
other speech, but it is first and most a braille daemon; I'm not
claiming it would be competition with vo for speech. If as you say
the ability to read the screen is there for all to use, why does
apple not respond to inquiries? And if the ability to see the screen
is so available, and somebody on this list has accessed the
information, it would make more sense to share that with the brltty
developers than to start your own project.
