I believe an older version of dmix used to act like a daemon, but the current version no longer does this and instead uses some magic spells that I don't even being to know about. As far as userspace mixing goes, most linux distros and a lot of embedded systems (e.g. smartphones) now use PulseAudio which does run as a stand alone daemon and opens a single stream to alsa. It does much more than just mixing, but it fits in with your paradigms :) See http://pulseaudio.org for more info.
