Accessibility wish list

Here's a list of the accessibility enhancements I think are desirable in 
the FreeBSD base system and documentation:

- Provide a VTY screenreader (which one?) in the installer itself, as 
self-configurable as possible, and that can be started on the initial 
menu with a simple key or key combination.
- Add a VTY screenreader (probably the same one) to the packages 
available from the installer so the installed OS can be speech-friendly 
from the first boot.
- Check the installer text and background colors provide enough contrast 
and or offer options to change them.
- Document the accessibility options added to the installer and 
available for VTY-only systems.
- Make sure all of the documentation and website is fully accessible. At 
a minimum, this requires checking all images are appropriately described 
and text contrast is enough to be readable by people with low vision.
- Likewise, for color blindness.

Other possible features I can think of but am lacking the knowledge to 
describe in detail and provide suggestions for:
- Speech recognition instead of a keyboard (that's a very tough one, 
maybe untractable - accents, spelling variants, ESL speakers, and I'm 
probably missing some).
- Other color schemes than white-on-blue (installer) or white-on-black 
(out-of-the-box default for VTYs), both configurable from the installer 
including for the installed OS.

Anything I'm missing? I'm going to put up a FreeBSD wiki page from this 
and any suggestions I get and link it here, but I wanted to start a 
discussion here for people without a wiki account.
