Ok, now it's clear, thanks for all your answers! Now the idea of a minimal ubuntu it's not too bad even for me :) and maybe is the best choose for your project. Pure:Dyne will be alwais my first choise for a live-system, but for my box I've decided to return to Arch, I simply can't live without pacman! :) I just joined the Archaudio group, and I think that this discussion helped me to take that decision, so, thanks to all. Go Pure:dyne!!
