A slightly crappy alternative would be:
  1. Make sure the audio devices are group owned and group writable by 
e.g. an "audio" group.
  2. Make sure all your users are in the audio group.
  3. Assign each user to a head and hard code the default.pa file to 
load only the specific alsa device they should use.

This is not ideal as if you swap round, your sound devices will stay as 
the old ones which is not very nice.

Console kit is responsible for assigning ACLs to hardware for the 
"active" user. This is how things are working these days and I think the 
only proper solution is to ensure that console kit is multi-seat/head 
aware, allowing the tieing together of a graphics output card/port and a 
sound device. This is way, way beyond my knowledge of consolekit tho'.!

 From the original announcement, it seems that this is a goal of consolekit:

I've no idea about it's current state of affairs. Perhap the hal mailing 
list is a good place to discuss/ask about it?
