That's awesome! I never would have thought you could run a full DAW on a Pi. It appears that all the audio is being streamed from disk in the video of the article you linked. I think down sampling would actually add a bit of overhead, but it's probably negligible. Would definitely be interesting to see how the Pi performed while recording to the SD card.
One thing I really like about this is that, between both DAW and VST's supporting linux, it's super easy/affordable to maintain a separate machine that is solely for music production.
