We all agreed to do this -- or Jimbo suggested this, I forget which:
1. Make a good faith effort for mediation. That's what the Mediation Committee was formed to do.
2. If this results in a good solution, announce the solution and that's the end of it.
3. In case mediation fails, the Arbitration Committee will do its thing and render a decision. Hang 'em at sunrise or slap his wrists: i.e., permanent hard-ban, temporary ban, edit quota, whatever they decide.
4. If this works, that's probably the end of it. (Reincarnation to evade a ban is usually handled by developers examining IP logs, etc.)
5. A "banned" user can appeal to Jimbo, who may veto the Arbitrators' decision.
We are still at step #1 on MNH. It's our first case, and we want to do this right: please give us extra time.
