@silverpill @reiver @xmppbrasil @helge @badrihippo @zoul i think with the way you're describing this case, it would really end up being a collection server or endpoint, right? that makes sense if there's a requirement to dynamically page collections. if you're willing to accept static collections, then it simplifies things greatly
but you could still keep side effects if you somehow signaled which clients attached to which inboxes and what they do. a "default client" can manage AP side effects
