Maybe it shouldn't be done by applications, unless the streams of an
app use different priorities.
It might be useful to look at configuration of networked apps in a
broader sense, including stuff like to what IP addresses and ports an
app should bind. Maybe even to what Unix sockets or other transports.
Being able to configure this in one central place is way easier then
having to dive into the conf file of each individual application.
In this central place the QoS stuff could be configured too.

As this doesn't require application support, it's probably easier to
implement. It also provides more flexibility and maybe even more
security.
