That could indeed by some handy functionality.
In pulseaudio there's already a concept of corking a stream. If a
stream is corked, its audio is muted and the application receives a
signal so it can pause the playback. If the stream is uncorked, the
music resumes playing.

This would indeed be best implemented as a module. You can use
module-cork-music-on-phone as an example.
There were also some threads on the mailing list about corking streams
that you might want to read, such as "dynamic routing through pulse
audio" a couple of weeks back.
