Well, yes, but there still needs to be a driver behind a brlapi server
to be able to driver the actual braille display. BrlTTY is a good choice
to avoid reimplementing it, since you can at worse disable its screen
reading facility.

Sure, there's a code snippet in pydoc brlapi.

BrlAPI is independant from how the device is actually connected, that's
the matter of the driver behind the BrlAPI server.

They're quite coupled as they need to interact to display braille, get
keys, etc.  But they don't really depend one on each other: you can
disable BrlAPI at BrlTTY build time or run time, and the brlapi server
and client code is in separate files, which we plan to move to a library
when we get some time, to make it usable in other contexts.

Then install the python bindings for brlapi and read pydoc brlapi.
