FYI - The Yggdrasil Screen Reader Project

[Linux for blind general discussion]

If fenrir is run correctly it can handle a g.u.i. terminal.  I never heard
of using brltty for this purpose but will try it out a little later today.
Orca has only one developer who is funded by her employer to do the
development.  If ygrazil gets more developers than one development will be
slowed by communication between developers by the square root of the
number of developers.  This is a well-known software development metric
among others.
