One of the biggest problems I feel which new users have to face is the audio issues. Ubuntu has gone down the route of using pulseaudio, which may be good enough for someone who uses audio for music, internet radio, etc (essentially are only sometimes using audio and possibly an audio failure is unimportant), but I feel pulseaudio does not do it for someone who is continually using audio (eg. a blind user using speech output). These issues range from audio mixing (we need speech and music or other audio to come through, where as I imagine the typical computer use of audio normally is one sound at a time, could you listen to music on your computer and internet radio at the same time?), latency (for speech a slight delay on output for every orca announcement really impacts on how fast I do things where as a slight delay when listening to music doesn't make a huge difference) and stability (although I don't have experience of pulseaudio I have heard some complain about it, if I loose audio I loose speech output and if I am using speech only then I have no way to access the system to find out why I have no speech).
People on this list have described how to configure ubuntu for ALSA as audio system, and this is the direction I would go, ALSA supports software audio mixing, responds quickly (I don't have figures) and is implemented as a set of kernel drivers and system libraries (no userspace daemon process which can die). Where a sound daemon is needed (eg. gnome system sounds) then ESD with ALSA output can be used (this is what I am doing here).
As for your question regarding applications which are run with greater permissions, this can be solved by creating ~/.obitrc files, I believe the Orca wiki does describe what to do.
In a way I feel OpenSolaris does fit this (solves the two main problems I have discussed), but the lack of openoffice on the LiveCD does make it very much something you would want to install rather than use as a LiveCD. Also the number of sound cards OpenSolaris supports by default is quite low so could pose issues there for being a generally blind friendly disto. This issue of what to include on a LiveCD is one of the most difficult questions for those creating LiveCDs, do you want it as a LiveCD or a installable disto? I mean should applications like OpenOffice be on there or should it be excluded to make space for something to make it work in more situations (eg. support more hardware)?
