Hi Ramón,

I do not have a perfect answer yet, because one pre-requisite is not yet free of charge:

if you have Adobe Acrobat and download and install the free "callas pdfGoHTML" plug-in (from http://www.callassoftware.com/callas/doku.php/en:download ) you can convert your accessible {DF's content into HTML and open it in the default browser, giving you access to all that (based on VoiceOver and its support of HTML content in a web browser).

We hope to also be able soon to launch a version of callas pdfGoHTML for the free Adobe Reader, which will bring down the additional cost to zero.

I've prepared a simple example of an "accessible" PDF document to illustrate the issue. You can access it here (I apologise in advance if I missed something and it's not completely accessible):

For blind MacOS users it is not necessary to spend any money on any kind of software in order to read a pdf document unless our Mac here in the office was magically equipped for us because they had a glass ball at Apple and knew that we are blind here. It is no problem at all to read those documents as long as they are readable i.e. are not composed out of graphics which would be the same for Windows users.
>> So, unless you ment something completely different which I did not understand you are wrong here.
