I think the note should be softened as well.  While Benjamin's email points out
many interesting methods that can be explored to expose some types of
visualizations to certain kinds of non-visual users, they are still limited
(most wouldn't apply to spiders) and most are both experimental and fairly
complex, rendering them unsuitable for authors at this time.  Even if we had
the hardware APIs necessary to implement an audio-haptic mapping of my
mandelbrot set generator (we don't), I wouldn't know how to use it properly. 
This is the sort of thing that still requires a ton of research and study, and
likely will only be truly usable when it's driven by a sufficiently intelligent
automatic system rather than implemented manually by authors.
