much info is available through mark up in the source, and I'd hazard that if 
someone wanted it the could either dig through the source for it or they 
could find an inspector either human or non human to get it.  Jaws can for 
instance provide tons of info if you want it.

Taking this to the extreme, though, visually impaired users may then
also want to know what typeface is used for headings, body copy, etc, what
colours, what patterns, what type of layout, etc

Again, the question here really is: what purpose do all the decorations
and other visual cues have? Is it really that relevant to a blind user
to know that the typeface used is Helvetica Neue rather than Cooper Black,
that it's all soft pastels rather than day-glo primary colours, if the
relevant associations and emotional responses that these visual cues were
used for are also present, in different form, in other parts of the 
page/site?

Debatable, and it would strongly depend on exploring *why* users are coming
to a particular site (compare a bank website versus an art site, for 
instance).

Anyway, my GBP0.02
