Thank you all. I will use the Curator recipe, since I already use Curator for a bunch of other things.
If curator can find the leader and the participants that is good enough. Otherwise I will parse the protocol buffer contents, and provide a way to parse the future son contents when that happens. I’ll reply again with the results of using the Curator recipe to get the leader and participants.
