Bluesound Vault Combined with Node 2

I have a bluesound node 2 connected to my high-end stereo system (Krell amp, Thiel speakers) in my living room. I am getting the Vault 2i to replace it, plus house all my CDs (over 1000). I have a second stereo system in my bedroom (Nad amp, Polk speakers) which I use with a grace digital Internet radio. Would there be any advantage for me to replace the grace Internet radio with the node 2? Can the node 2 and the vault “talk” to each other so that I can play my burned CDs from the vault in my bedroom? Any other suggestions of what I can do with both devices would be gratefully appreciated.
