Logitech Media Server with DSJ?

I have Logitech Media Server (LMS) running on a dedicated (Synology) NAS which connects to my Squeezebox Touch via Ethernet. I use iPeng for controlling music selection and playback. I’m thinking about replacing the Squeezebox Touch and PS Audio DLIII with DSJ. Will iPeng still work the same without the Squeezebox Touch? I’ll still be running LMS on the NAS, and I’m assuming the DSJ will interface with LMS without problems. I don’t know whether iPeng talks directly to LMS on the NAS or to the Squeezebox Touch.
