Yes, Dane Via is an interesting technology and if it would have been possible to run in on it on a Raspberry Pi, using Rasbian, it would have been a very, very interesting option…
Apart from wishful thinking, I don’t think it’s possible to run Dante Via headless (without monitor, keyboard and mouse) without logging in to the computer (autostart when turning on the computer). This is would be what’s needed for a permanent install. Another problem is the fact that this system would be used maybe 5 – 10 hours a week, which would make a computer running 24/7 a big overkill (how do you turn on/off the computer without user intervention?).
