@garbados @samis @h I was thinking of using dat's append-only streams because that's a lot easier to deal with for maintainers as they can just put as many packages in one stream as possible, increasing throughput down the road (I'd explain it but it's too long to fit on this thing, but basically downloading the next package doesn't require you to open a new connection). then the package manager can just do "fetch packages from these and these streams, fetch package DBs from these streams". you can also still have full mirrors.
