Knowledgeable people in the Boston area

I know that some members of this list are in the Boston area; I'm also wondering if any of the "names" in crypto live up here. I'm trying to arrange a talk (elementary level) for a group of human-interface designers I chair and am hunting up speaker ideas. I will be out of the office tomorrow, but will respond to emails Monday.
