Under the current design, yes. It's actually probably going to be a bit more complex than that, changing to a 'minstorage' which is the minimum amount of storage you can join the network with, and then a 'storageperswarm' which will be much smaller than that. Hosts will be participating in dozens to hundreds of swarms each, but each swarm will be moving substantially slower, keeping the overall network traffic the same volume. Overhead should stay below 1%.

Tentatively anyway. I'm working on it.
