Although now way off topic, it may of some interest to share some of
my findings on this.
Although I have been looking at several places. Two web sites that
are actually useful are:
http://www.webaim.org/
AND
http://www.open.ac.uk/inclusiveteaching/index.php
The conclusions from all my reading is that only HTML fully qualifies
as accessible, because it provides all the features (if properly
created) that are needed by on screen viewers.
PDFs CAN be fully accessible, because you can add the tags and the
alternate text needed to direct text flow and provide alternate text
for images ( the latter you can also do in PowerPoint).
It seems that while HTML has the edge over PDF, they are very close.
PowerPoints are NOT considered "fully" accessible,because they lack
essential features. The advice is to convert PowerPoints to HTML,
and provide these as alternatives to your PowerPoint,
Additionally the Webaim site recommend writing your presentations in
HTML to begin with and suggest Opera Show or S5, which work like
PowerPoint but designed to use HTML. Thus making them in the format
required for uploading.

Opera Show is built into the Opera Browser, the browser I used before
switching to FireFox, and an Opera Show tutorial is at:
http://www.opera.com/support/tutorials/operashow/
Both are free.
What I need to do now, see whether Lyx/Beamer/Latex will allow me to
create HTML files with the appropriate tags and alternate text for
figures that are needed.
As I say not really a lyx issue, but it may be of interest to some.

I would prefer a Mac or multiplatform option, but Windows, or even
Linux would do.
Having now been using Beamer for a few days and been very pleased
with it as a replacement for PowerPoint, I'm now told that I "must"
provide my students access to PowerPoints of my presentations.
However, having used Beamer there is no way I am going back to
PowerPoint.
Apparently, PDFs, do not provide the same support for accessibility
requirements (SENDA in the UK and section 508 in the US). I can't
see how exactly, but thems the rules it seems.
