Well, wasn't the supposed problem with transferring "the whole stream"
that the data rate is needlessly high that way? If you use a
sufficiently low sample rate, then the data rate is just fine. It just
turned out that monitoring a tunnel sink can prevent the sink from
suspending, which hopefully is fixable.

The current peak detection mechanism smells a lot like a hack, but I
think it actually works quite well, so I don't see the need for adding
separate peak detection features to the pulseaudio protocol.
