I am very interested to see where the conversation goes, because I have written a deaf character into my current project (and much of what I did with her scenes is based on what I learned from the panel on disability at CONvergence). It has been difficult to describe the communication process when my characters are not vocalizing their dialogue. With a blind character, you don't have to make any special notes about their dialogue, they can just "say" things.
