AP-linux: Is a realtime kernel or JACK sheerly for music playback really necessary? I'd say no.
Looks fairly cool for multiple streams, recording stuff on a middling system. Love the fluxbox and deadbeef..err, love. But if it only wasn't so easy to take a snapshot of the EXACT SAME setup on my Arch install and put it on a Live CD...Heck I could just churn up a system with nothing but cmus/mpd and ALSA, run it bit-perfect without dmixer, slap it on a P3, and call it a day.
*Actually, when you look at the screenshots, it appears to be just a snapshot of Linux Mint (couldn't just start from scratch? ) with audio set up and stuff stripped down. Way to innovate.
