Most browsers (except I think MSIE for Windows) have a control for 
zooming the text size.
If your layouts+css use relative units of measurement (like em) then 
this can provide a smooth resizing of page content and layout.

CSS has an 'audio' component for defining how content is spoken in 
browsers designed for the disabled.

Accessibility guidelines rely very heavily of having the right 
descriptive meta data available for specialised browsers to provide 
hints to the user.

If this meta data is not available in your content, no amount of clever 
stuff from Cocoon would get over that.

Will test your pages for Accessibility issues defined in the's 
WAI initiative.
