Great discussion point Jimbo, although I don't think discussion is actually required, the foundation should be able to just do this without the support of the users that are disputing the edits. In really difficult disputed issues I agree the wikimedia Foundation could hire experienced editors, although I wouldn't support any wikipedia connected interviewers, use and pay someone totally independent - independent notable reporters to interview and report on the problematic content issue and report that in a wp:rs source thus giving full independent closure to the dispute.
