Ah, so what i’ve been referring to as streaming/mirrored relays basically! I’m looking forward to seeing more and more relays with that functionality.

I like this idea as well. I think NVK is calling them buffer relays. I can imagine having a self hosted relay that is connected to x number of relays and aggregating notes and filtering out unwanted content. When I am on mobile I only need to connect to my self hosted relay. Now I am only retrieving data I am interested in while on mobile.
