I've pondered the idea of a mechanic like this. The problem of relying on the party leader to be the managing addon is the occasion that the party leader may not be running your addon. The easiest way to go is to incorporate a ping/response system with a random number generator. It would be wise to have the newest version moderate the other copies of your addon as it can both handle any new features and provide backwards comparability if needed for older versions. If multiple copies of the newest version are running, you can have each publish a random number, If a copy sees a higher random number posted in this phase, it shall remain quiet until reset.
