Sure, but the problem remains. You can't expect a user to download a tool and then configure their OS to limit the application. Developers / Linux users might do that, but someone on Windows or OSX won't, I don't think the OS even exposes those controls to the user in a easy manner.

So, while we get there, applications/tools can also manage their bandwidth, so the default settings are more gentle with using users bandwidth.
