Hi,
This story with the completely blind user has another question - how will such a user work with the computer screen and on the computer at all. Anyway.

RE: Live CD
The Live CD is more than O.K. In my view a specification or a quick reference guide in style expert system should be done what the newcomer may or should do after installing the Live CD.

This Expert Guide could be something of the kind:

If you are this and tthis and this case (i686 PC architecture, Desktop, Freelancer) - you may do this and this (install the most appropriate APPs)

If you are a server case - proceed with this and this. ... And don't forget to acquire competitive advantage on the market by installing ClamAV and ClamTk, etc.

If you intend to organise SSH tunneling through HTTPs at 7th level of firewall protection - install Apache server, and do this and this, etc.


Regards
