"Using Macromedia Flash Player 8, people with visual disabilities may now
access the web using either Window-Eyes from GW Micro or JAWS from Freedom
Scientific" --

So "accessibility" (which Adobe doesn't define) can be made available only to
users of two specific products. (Not to mention the specific versions of
those products, and the specific environments that those products require.)

I would imagine that if it were possible for Adobe to provide Flash
accessibility for any browsing environment, they'd prefer that -- likely to
be less work than having to develop accessibility for individual browsing
environments.

So when speaking about Flash, it would seem that there is no such thing as a
generic "accessibility" and that such a thing is impossible.

And that's only considering one single plugin.

I'm not sure I understand. You mean like <video src="movie.ogm"><a
href="movie.ogm">watch movie</a></video>?
