Hi Herman,
Can you enumerate the most important non-free pieces of software, firmware and drivers, so we can figure out what is missing to from a completely Free music- and audiovisiual workstation?
I'd say the alsa audio/midi device firmware is probably most important. I don't know if ffado contains any device firmware, or needs to upload it. Wi-fi firmware like the bcm43xx driver uses is important for mobile users, but not everyone of course.
Cheers! Daniel
