Bill said in the december 4 2003 meeting:

Willy- no response from Mario Lang about participating in the I/O area.
Bill- need him for the Braille API licensing.

Now I quote a mail I sent to this list several weeks ago:

Bill, I am since then waiting for any sort of positive
or negative reply to this question.  Since you were the one who
raised the concern with BRLTTY's licensing, I think you have
the expertise to answer above question.

In general, the BRLTTY Team would be willing to relicense the
client part of libbrlapi.  I do not know if this would
suffice.  I am quite willing to coordinate this license
change with BRLTTY upstream, but I rely on feedback from you.
It does not make much sense to change a license now, and realize later
on that it didn't have the desired effects.
