But they do allow you to pick which IP address you are going to send stuff
to.

I would hope you are. Why in the world would you want a fascist operating
system telling you which sound interface you have to use.

Why would they assume that? That is a stupid assumption.

You are the only one who knows what the "right" device is. Thus you are the
one that should tell it

This is a joke right? As well as? That is a totally fascist operating
system in all respects.

I still do not understand why writing a hotplug script is so horrible, if
that is what you want it to do. That is where this kind of stuff belongs. 
"I plug in X, When I plug in X I want Y to happen". That was what hotplug
scripts were precisely designed to do.
