...but in the meantime that content will be available to nobody? (unless
they're using Prince XML)

I don't think there's any media type of media query property that can be
used specifically to target "screenreaders", and I doubt there will be
in the near future.

Heck, there's no way to specifically target "handheld" or "tv" - even
though media *types* for those actually do exist - they are simply
ignored by all user agents on those particular devices because,
historically, they have been used to send "lower quality / lowest common
denominator" type styles to old devices (exceptions here: Opera Mini
reacts to "handheld", but only if users have enabled the "single column
view" option, and the only major device that obeys "tv" is, to my
knowledge, the first generation Nintendo Wii internet channel, i.e.
Opera 9. (full disclosure: I work for Opera, but I'm not saying these
for promotional purposes, but because I believe they're technically
accurate).
