This is already in there in plain Xorg: you can use the brai layout. You
can use a key to toggle between two groups, a classical layout and the
brai layout.

You can then define the computer braille - text relation in .XCompose,

<braille_dots_1> : "a"
<braille_dots_12> : "b"

grade2 input can not be done through the method above, however. One
would have to implement an xim/scim/whatever module for that, which
could also implement grade1 instead of doing it by hand in .XCompose. It
should probably be based on liblouis to make the translation.

This is rather a request for the Linux kernel, as Xorg does not manage
bluetooth devices.
