Michael, this is the talk I had remembered. It was indeed about conversion
to DAISY, not Braille. Sorry. If one could find a way to convert to decent
DAISY, however, then liblouisxml would, at least in principle, be able to
translate it to decent braille. I have more faith in the latter than the
former however. My experience with PDF makes me very skeptical that you'll
ever be able to convert PDF to any accessible format automatically for the
types of PDF you describe.

I have had a look to see if I could find what you were saying about, I
found something by Prof. U. Nikolaus talking about what would be needed
for automatic PDF to DAISY translation. I don't remember seeing anything
on PDF to Braille. Do you have a few more details to help me track down
the correct talk?
What I found wasn't very helpful for what I need, it seemed to be more
getting at what the ideal PDF would need for it and as I said the PDFs I
am dealing with aren't perfect in any sense.
