We have no trouble with the idea of Audirvana-style memory play, and we’ll probably implement it at some point.
@audiomuze is right too–decoupling the endpoint from the media server is a more complete solution to getting the audio away from the computer stuff. Right now, Roon remotes help you accomplish this, but that’s sort of a stopgap in our view. RoonSpeakers is the longer-term solution to this problem, particularly hardware implementations of RoonSpeakers.
