Accessability in Edubuntu

[Jude DaShiell]

I can tell you exactly how well orca will work in a thin client 
environment and I can explain why.  Orca requires a thick client to work 
at all, and it requires broad band access.  Without those two components 
in place it will not work at all. This is why.  The other name for thin 
client is dumb terminal.  That means you get a keyboard; a screen, a 
network connection, and nothing else.  No memory; no hard drive, no 
floppies no speakers, no connection for refreshable braille display, and 
no way to do screen magnification without additional hardware. With a 
thick client also known as a pc equipped with all the dangerous stuff 
listed above the thin client/dumb terminal hasn't got, maybe orca can run 
provided it can talk to the environment on the other end through a pipe. 
Well jaws and window-eyes work that way at least require pipes.  I know 
about this stuff because a system that will be expanding in the coming 
years uses citrix where I work and they're most likely going to take it to 
narrow band so screen reader users will need to use dos or command line 
linux if required to access that system.  Why dos rather than windows and 
why command line instead of X in Linux?  Simple, all that pixel grabbing 
the graphical user environments do to figure out what to communicate to 
you takes up band width since they're pulling it off the net constantly. 
Dos and Linux ommand line applications only need characters not pixels and 
for every symbol on the screen to get generated that's 143 fewer pieces of 
information for dos and command line linux than it is for any of the 
graphical user interfaces.  If I'm not mistaken 12x12 pixels in a 
character but I probably ought to take the smallest screen resolution and 
do the math on that vertical*horizontal/2,000.  All of this stuff was 
known and documented as far back as 2001 and put out on the web.  I found 
a paper by a writer from R.N.I.B. with this information in it earlier this 
year.  The reason for using narrow band is to help security.  With minimal 
resources available and minimal speeds possible because of minimal 
resources a network take over even by someone who managed to tap into the 
right network cable becomes infeasible.
