These traces correspond to volume changes in the web interface. No trace
at all when using the touch surface on the Zipp Mini.

So I fired up iTunes on my OS X desktop (172.17.255.15) and obtained
this when changing volume on the Zipp (172.17.30.2):

It is quite curious but the Zipp and my server don't seem to exchange
