We want to integrate p2panda-spaces into the high-level API so you can conveniently add / remove members to groups which will allow us to encrypt everything towards the group's encryption secret, probably again scoped around a topic.
Having a key agreement system like this protects your messages when relaying them across intermediaries, like "support nodes" or in mesh networks, with Post-Compromise Security and Forward Secrecy!

Support nodes are nodes which are "more online than others", which can hold onto your data for a while so everyone can download it from there when nobody is online. This is similar to DeltaChat's Chatmail Relays or MeshCore's Room Servers. The trick here is to encrypt your data fully, so no meta-data is leaked whatsoever before storing it on a support node. Applications should not bother about what's going on here, they just want to add / remove support nodes and manage access to them.
