I'm pretty late to this thread, but I too like the "masterless" approach. I was thinking that KeyClone might be able to do remapping, but never took the time to look that far into it. I can't wait to get home and try this out.

I'm going to shamelessly plug here: If you like to go "masterless", you may like my addon, MultiTool, for this as I specifically made it to just silently make stuff work (quest gossip, auto accept escort quests, auto accept summons, auto accept group invites [white-list-enabled], auto follow taxi) without the traditional "master/ slave" relationship.
