unity3d is somewhat accessible with orca, but as you note the dash and 
some other stuff isn't really working. Zooming doesn't work on the panel 
and launcher (except for the badly implemented and annoying top bar 
shadow . . .) because that is all drawn through the nux toolkit which is 
unaffected by any compiz transforms. I know this is really bad for a 
huge number of people with mild to moderate vision issues (almost 
certainly our largest group of users of assistive tools - basically 
anyone who might wear glasses and enjoy the large print section of the 
local library) and I will be raising this at the Ubuntu Developer summit 
next week.

unity2d with compiz might be a better strategy, and in fact unity2d with 
the Wayland compositor might be the real way forward, I have been 
talking to the wayland developers about accessibility including orca and 
zoom and text cursor tracking zoom and colour filters, it is important 
to get this stuff in as early as possible and designed in, rather than 
tacked on afterwards. With features like the HUD landing broken and the 
global menus all being checkbox menu items until we got the hint set 
right and the shortcut overlay being totally inaccessible it is clear 
that accessibility isn't being designed in early enough to new features 
and this is creating more unbudgeted work as people try to fix the 
broken stuff that was never designed to be accessible.
