above is an address of someone who has developed a open source
augmentative communication with a program for the computer he is looking
for developers in Linux and OSX.  The above address is for those
interested in helping in this matter, if I knew enough I would do it.

Pearl knowledge is needed, Please could someone there do this for the
children of autism and non speaking.  

Thank you 

Mom of an autistic child.
