Fair enough, I'll have to rephrase that in the next version ;-)

What? You gave me the same link as I gave you!
My point is that the HTML implementations are pretty terrible. I still
believe it is a style rather than a structural concern; then you can use
@media aural

Possibly an alternative quicker table of contents, for example, instead of:-
[home] [section 1] [section 2] ... [mail us]
You could point it to a file containing:-
[home] [mail us]
My examples are always crud, so I urge you to think of a better one if you
see what I am talking about ;-)

Yes, but what about an alt for ASCII art of something? They can't have alt

Yes, but see my arguements above!

I belive this is a useful WAI CSS implementation: anyone that uses a voice
browser will *emphatically* agree with me. Adding a simple line to a CSS
stylesheet could save people having to change navigation bars on hundreds of
