Ok, how about giving the option to deploy audio as either 
1) Direct to card hardware 
   Card set up as /dev/dsp hw:0 etc 
2) Software Mix
   Dmix set up as /dev/dsp hw:0 etc
   Following audio devices set up /dev/dspX hw:X etc
And the future kernel hack
3) Multiuser Software Switch
   a /dev/tty like switch for /dev/dsp hw:0 to each users assigned 
    /dev/dsp hw:0 etc - either hardware or dmix device.
