I am beginning to follow the guidelines of the W3C Web Accessibility Initiative (WAI)(http://www.w3.org/WAI/) , to achieve better accessibility for impaired persons and for content filtering (not only for children). I have also written a document about Linux on mobile computers for blind people.
The TuxMobil pages are available in different formats, e.g. for printing, WAP, i-mode, PDAs and more.
