That was going to be my next challenge.  Even on windows, there is variance 
in what AT and UA support.

I have yet to get opera to work with VoiceOver.

But I qualfied what I meant by "all browsers".

The built-in screen reader of Mac OS X - VoiceOver does not
support @longdesc. VoiceOver is based on WebKit - aka Safari.

This leads to this strange contradiction: While Apple's Safari
supports @longdesc, their Safari based screen reader doesn’t. (The
same contradiction applies for the screenreading support in Opera
on Mac OS X - which also uses VoiceOver.)

Anyway, my point was to say that the support for @longdesc is much
better than Lachlan claims simply because all the mayor browsers,
on which the screen readers usually are based, they support it.
