Speakup really ought to move out of the kernel entirely and be made to 
work as a regular process like Brltty does. Yes there might be some 
politics behind this, but it is by far a flexibility and ease of 
maintenance issue.

And it wouldn't be hard for the kernel to export the needed information 
to user space. Speakup already relies on special notifier hooks located 
in the core kernel console code to figure out what to speak. Those same 
hooks could be used to transmit the same information to any interested 
user space process as well.
