Pipelining allows rendering and app logic to run in parallel. You can adapt to changes from the network when the app logic runs, so in that sense, it seems like a good fit. And you can use bevy_tasks to spawn background tasks (and spawn tasks across different thread pools, if that is required). I think it is worth considering Bevy, but I also think Rend3 is a great piece of software. We discuss rendering with that project's lead constantly :)
