Hans, 1. Would a clause that said: "One effective technique in operating sytems that use separate process spaces for providing timely access is to allow assistive technologies to run in the same process space as the user agent, thus eliminating inter-application communication delays" 2. Do you have any examples of what techniques would be useful on a Macintosh operating system to support inter-process communication?
