So I was thinking more about this… If you wanted to have a user group-hosted cluster with no 3rd party, and the app would be hosted strictly on user owned devices (or maybe devices leased through a separate agreement with a private hosting provider), is this more what you had in mind?:
Alternatively, if you wanted to allow users in the group who don’t necessarily host, or needed to access the app from devices which are not a cluster node, maybe:
No worries! I actually really need to find a solution to this problem as well, and it helps to talk it through 
Possibly in the future, or maybe on the dgraph slack channel, but would like to keep having the discussion here in hopes that we can tie it in to a couple threads already started (Multi-tenant solution for Dgraph and Ultimate user privacy scheme) for a holistic solution to this problem possibly involving new dgraph features
