There's something I just noticed about my 1st gen one that I didn't like, last weekend a friend came over, he has a Node at home as well, and he connected to mine to play some Spotify playlists, It's all fair is good, but he was able to play music in my system even when he got back home. It's a quirk I don't like, I don't know yet if it's my firewall and security settings that are deficient, or if the Node player can bypass all that and get straight to the IP inside my LAN, but it's invasive. Maybe Amir had problems for a reason, It appears Bluesound like to have a lot of freedom when it comes to the network.
