After finishing the first implementation of Russound support, I figured it is easier to demonstrate this with a little video then writing a long story
Currently the Russound commands are configured inside a property file  so it is easy to extend.
We support 6 zones and 6 sources in the moment. Each zone can be turned on/off, the source selected and the volume changed.
When the server push is working, I will try and implement feedback so you can see which zones are active and which sources are selected.
Also, I want to use a slider to control the volume. So look out for a new version

Enjoy the video!
