I had this question after viewing DANE and Convergence
Who sets up the notaries in convergence? Is an administrator required to oversee and how can we be assured that there will be many notaries to choose from? For DANE it seems as the trust is left with the domain owner rather than a third party. Isn't this still a concern for man-in-the-middle attacks? What are some negatives for using these methods if they do gain traction?
