I'm glad the author thought about screen readers and other accessibility software. Yes, easy support for alternate input methods helps. But for screen readers in particular, the most important thing is a way to access a tree of objects representing the application's UI. Doing this efficiently over IPC is hard, at least with the existing infrastructure we have today. Edit: I believe the state of the art in this area is the UI Automation API for Windows. In case the author is reading this thread, that would be a good place to continue your research.
