Hi, We have made a few changes to the document: 1. Added in support for Network Proximity (this will be exposed by Quantum) 2. Following upstream reviews we have added in the proposed API for the group deployment. At the moment there is a hint that enables group affinity. Hopefully we will get to discuss these at summit and then be able to move forwards. The updated document can be found at: https://docs.google.com/document/d/1A2CYUI754q5g14b7LhbNz7onZcDqOxz_Ba5fuO2Myro/edit?usp=sharing Thanks Gary
