 c. Existing software, partial solutions, etc.  Implementations of the
    proposed standard should already exist (usually produces a less
    buggy standard), or should exist in approximate form (for example,
    no Unix complied with the first POSIX standard at the time it was
    being written, but many were close), or there should be an
    indication of what new implementation work will be needed.

We benefit from the fact that the greater majority of requirements to
support users with disabilities are well understood. Several generations
of technologies for supporting users with disabilities have previously
been implemented, sometimes on several platforms, though usually on
proprietary ones. The value and viability of such standards is,
therefore, well established. The most comprehensive solutions available
today were created for Microsoft Windows computers. An incomplete
solution has long been available on Macintosh computers. Elements exist
for free and open platform desktops, and significant robust solutions
for certain user communities are well established on the console side of
free and open platforms. Examples include:


*keyboard accessibility:

**	end-user features:
		AccessX,
		Gnome's Keyboard Accessibility Preferences Dialog
**	APIs/ABIs:
		XKB Specification, X.org

*Accessibility APIs/ABIs: (i.e. existing open solutions and also prior
art
                         in the proprietary domain):

**applications-side:
		ATK
		Java Accessibility API
		UNO Accessibility API (StarOffice/OpenOffice.org)

**	assistive-tech client-side:
		Java Accessibility API
		Mac Accessibility API
		GNOME's Assistive Technology Service Provider Interface (AT-SPI)
		Microsoft Active Accessibility (MSAA)

*Accessibility-related utilities:

          gnome-speech text-to-speech APIs
          gnome-mag magnification APIs
