Or if it's a USB sound card, use that device while pluggged in then fallback 
to the other sound device when removed (but that could be backend dependent)
IMO, this should be transparent. Of course, display a passive popup to inform 
the user that a new soundcard was inserted.

So we will have a global Phonon configuration that applications will be able 
to override ?

Look fine to me (query backend for capability), as long your fix problems with 
device sharing of course ;)
