As the sharing of courses will be a proof-of-concept, account creation/grade transfer could be done manually at the beginning (Q1 2020).
Later maybe it would make sense to use OAuth or alternatively eduroom logins.

The problem is that we should have a first running prototype soon and a production-ready site Q3 2019. So I am afraid that Project MoodleNet will be in a too early stage at that time.
Does it make sense to still rely on the community hub functionality?
At least the publishing part? So then we could also implement our own front-end client for the central listing of published courses. We just needed the respective web-services API.
