It’s still point to point, and not p2p or some kind of aggregation.

What it can do however is stream multiple Nostr subscriptions or events at the same time from the same relay - or perhaps even stream events and the media content like images at the same time without blocking.

At present if you send 5 large events and 5 small ones, the first large 5 events need to be received one by one fully before the faster smaller events can even start. Basically congestion.
