There is already an (old) patch that implements that. It won't be merged, though, until headers-first and parallel block download is in. Only when the node can download blocks from multiple peers at once it is really safe to allow limiting rates. (sure - there are tricks to limit rates anyway, like the script in contrib/qos, but to have it generally available the block download needs to be more robust first) Wladimir
