Two questions:

(1) Should assistive technologies have any weight, in and by themselves 
or or only count when seen from the browser angle?

    For example Apples AT, VoiceOver, does currently not support 
@longdesc. The reasons for this are that a) Apple's browser does not 
support @longdesc and b) no other browser with @longdesc support has 
been made to work with VO in such a way that longdesc can generally be 
used with it. But this could change when Firefox soon gets VoiceOver 
support - then VoiceOver probably gets @longdesc support to.

    So if one looks at the situation from a Mac platform A11Y user's 
perspective, then such a user would be able to use an AT that has 
@longdesc support once Firefoxs get VO support. Does this not count as 
anything in this math? (That's how what you say above sounds lik.) Why 
should it not be relevant to see it from the VoiceOver user and ask: 
"Can one use @longdesc with it? Yes, if you use it with Firefox. OK. 
Nice this will count positively."

(2) [This question is probably much simpler.] There are a large number 
of Webkit browsers, which vary a little bit with regard to what they 
support - e.g. accessibility wise. Would it only count if @longdesc was 
supported in e.g. Chromium or Webkit, whereas the derivate support - 
Chrome, Safari, iCab - should be looked away from? (I guess iCab is 
partly a derivate of "the Safari stuff" inside OSX and iOS too - its 
not only a Webkit derivate.)
