Suppose you're running a remote session, where artsd is running
in another computer, different than the one which is running noatun.
If you play a stream in your way, you would have an stream from
the streaming server to your computer, and then another stream
from your computer to artsd. If aRts does the whole work, you will
only have one stream thus saving network bandwith and CPU usage in
the computer where noatun runs.
