First of all, well done on creating such a easy to use and graphically beautiful piece of software.
I am wondering what happens if I wanted to run two raspberry pis at the same time. Previously I used two instances of Squeezeplug where you could chose which Pi to play the music on (or both at the same time). It worked quite well, but I was not pleased by the mobile interface.
So my question is, is there a way to play one piece of music in sync on two Pis?
