Interesting. I probably wouldn't drop my Squeezebox setup for it since it seems to require iOS (7 only??)/Andriod devices to control what's playing and doesn't yet support playing audio from a computer.
We are also looking at supporting DLNA or some other local music protocol due to interest we're seeing.
Btw, love Squeezebox, Dean Blacketter, one of the founders and CTO is a friend and advisor to us.
