Mmm, being able to read the console is quite dangerous: via an ssh
account, it's just spying. And being able to insert keypresses on the
console is even more dangerous.

I'd suggest to rather add a brl group that would have such permissions
(so as to limit people who have such powerful permissions).

Braille support starts fine with 'sudo brltty' so if we document it as such it should be fine. We are also developing ways of starting brltty automatically at boot and on the Live CD. We'll open new bugs instead to track usability issues arising during that process.
