Does anyone have specific styles for braille display? What would be different for a braille style sheet as opposed to, say, a screen reader style sheet? I seems to me that since you have the option of specifiying which style to use to which medium, there must be some difference. Can you make one style sheet or set of styles for a combination of screen readers, braille displays, etc?

Screen readers use the document structure to present content to users, so the styling (generally) isn't important.
I can't think of an example where a braille display would need a different style to a screen reader, and surely the braille display would be driven by a screen reader anyway(?), with the display using its own in-built logic to translate text content to braille.
AFAIK current AT does not support the aural and braille media types, and the original concept seems flawed anyway. See Joe Clark's chapter on Stylesheets [joeclark.org]. These separate media types seem like more of an academic exercise than something that actually provides RW utility.
It's probably more worthwhile to focus on providing alternative style sheets for users with visual impairments who are not using AT: for example a high contrast style sheet and/or a large text style sheet. Google "zoom layouts" for more info. HTH
