Legal Communication in Technical Communication Programs: Worth Thinking About?

What, if anything, should technical communication programs teach their students about the nature of law and the production of legal discourse? When is technical writing also legal writing, and vice versa; when is legal writing (really) technical? Are there distinctions worth maintaining and dissolving here? Do lawyers' relationships to, and problems with, legal writing contexts and processes parallel in important ways technical writers' relationships to, and problems with, technical writing contexts and processes? If they do, is a conversation between the disciplines worth institutionalizing, at least experimentally, in each other's programs?
