The ability to have a private conversation between two users throughout a review process is the given request from Comcast. Specifically, between a reviewer and a user making revisions. This would be outside of a standard review task or document level voting and would need to be surfaced on the task view. The ability to surface this conversation at any point during a workflow from a task, showing only conversations that a user was a part of. Ideally, it would be great to leverage Chat Boards for this functionality if we could build in a way to make conversation private between two users.
