[BRLTTY] brltty "keyboard braille device" support (and a few more things)

[Hermann]

Hi to all,
I used brltty and sbl together on a machine where I installed grml, a 
debian based system, available on a liveCD.
I didn't experience any conflicts, but both don't communicate in a 
strict sense, they run parallelly.
Because I'm not able to patch the kernel, I hadn't the full screen 
navigation sbl offers.
What sbl does, was to read in applications that have a system cursor. It 
didn't speak in the shell.
I remember that Samuel told me that there's no need to patch the kernel, 
if the sbl developpers manage to use udev (ist this a driver or an 
interface?)
I don't know enough about that stuff, so Samuel, could you please 
explain again, what it's all about?
If I understood well, it's possible to use sbl for screen navigation 
implementing udev.
Regards
Hermann
