[Accessibility] X-server moving part of its code into the kernel

There is a tremendous amount we can start doing for accessibility with
the screen display, base with the various underlying improvements coming
from Keith and freedesktop.org and the X-server changes. Some of the
things you cite below are things that are possible today, but at too low
a performance level to be practical. Other things are becoming possible
through things like Compiz or some other tight integration between what
the window manager knows and can do, and what a compositing engine knows
and can do (combined with specific accessibility logic and at the AT-SPI
infrastructure). At this point most of this potential is sitting in
folks' brains or sketched on napkins and whiteboards. I'm hopeful that
will start to change over the next 12 months.
As to whether and which of the specific changes Keith discusses in his
paper can/will enable which specific accessibility features - I'm an
insufficient expert of the underlying X layers to say.
For me, your sharing general X server developments/improvements with
this list is useful and newsworthy (with the caveat that any specific
one may or may specifically be of use to us).
