Yes, this is the default.

That's it by default (as described in the README file).

Indeed. But brltty can already do this right now, before 2.6.17: by
opening evdev and grabbing the keyboard, it can grab keypresses and
hence implement braille chords at wil.

For now, only unicode representations are emitted. But we can add an
ioctl for loading maps and then there brltty could just feed the kernel
with his tables and not need to handle them afterwards.
